# Labs features
|
|
|
|
If Labs is enabled in the [Element config](config.md), you can enable some of these features by going
|
|
to `Settings->Labs`. This list is non-exhaustive and subject to change, chat in
|
|
[#element-web:matrix.org](https://matrix.to/#/#element-web:matrix.org) for more information.
|
|
|
|
If a labs features gets more stable, it _may_ be promoted to a beta feature
|
|
(see [Betas](https://github.com/vector-im/element-web/blob/develop/docs/betas.md)).
|
|
|
|
**Be warned! Labs features are not finalised, they may be fragile, they may change, they may be
|
|
dropped. Ask in the room if you are unclear about any details here.**
|
|
|
|
## Submit Abuse Report to Moderators [MSC3215](https://github.com/matrix-org/matrix-doc/pull/3215) support (`feature_report_to_moderators`)
|
|
|
|
A new version of the "Report" dialog that lets users send abuse reports directly to room moderators,
|
|
if the room supports it.
|
|
|
|
## Render LaTeX maths in messages (`feature_latex_maths`)
|
|
|
|
Enables rendering of LaTeX maths in messages using [KaTeX](https://katex.org/). LaTeX between single dollar-signs is interpreted as inline maths and double dollar-signs as display maths (i.e. centred on its own line).
|
|
|
|
## Message pinning (`feature_pinning`)
|
|
|
|
Allows you to pin messages in the room. To pin a message, use the 3 dots to the right of the message
|
|
and select "Pin".
|
|
|
|
## Jump to date (`feature_jump_to_date`)
|
|
|
|
Note: This labs feature is only visible when your homeserver has MSC3030 enabled
|
|
(in Synapse, add `experimental_features` -> `msc3030_enabled` to your
|
|
`homeserver.yaml`) which means `GET /_matrix/client/versions` responds with
|
|
`org.matrix.msc3030` under the `unstable_features` key.
|
|
|
|
Adds a dropdown menu to the date separator headers in the timeline which allows
|
|
you to jump to last week, last month, the beginning of the room, or choose a
|
|
date from the calendar.
|
|
|
|
Also adds the `/jumptodate 2022-01-31` slash command.
|
|
|
|
## Render simple counters in room header (`feature_state_counters`)
|
|
|
|
Allows rendering of labelled counters above the message list.
|
|
|
|
Once enabled, send a custom state event to a room to set values:
|
|
|
|
1. In a room, type `/devtools` to bring up the devtools interface
|
|
2. Click "Send Custom Event"
|
|
3. Toggle from "Event" to "State Event"
|
|
4. Set the event type to: `re.jki.counter` and give it a unique key
|
|
5. Specify the content in the following format:
|
|
|
|
```
|
|
{
|
|
"link": "",
|
|
"severity": "normal",
|
|
"title": "my counter",
|
|
"value": 0
|
|
}
|
|
```
|
|
|
|
That's it. Now should see your new counter under the header.
|
|
|
|
## New ways to ignore people (`feature_mjolnir`)
|
|
|
|
When enabled, a new settings tab appears for users to be able to manage their ban lists.
|
|
This is a different kind of ignoring where the ignored user's messages still get rendered,
|
|
but are hidden by default.
|
|
|
|
Ban lists are rooms within Matrix, proposed as [MSC2313](https://github.com/matrix-org/matrix-doc/pull/2313).
|
|
[Mjolnir](https://github.com/matrix-org/mjolnir) is a set of moderation tools which support
|
|
ban lists.
|
|
|
|
## Verifications in DMs (`feature_dm_verification`)
|
|
|
|
An implementation of [MSC2241](https://github.com/matrix-org/matrix-doc/pull/2241). When enabled, verification might not work with devices which don't support MSC2241.
|
|
|
|
This also includes a new implementation of the user & member info panel, designed to share more code between showing community members & room members. Built on top of this new panel is also a new UX for verification from the member panel.
|
|
|
|
The setting will be removed in a future release, enabling it non-optionally for
|
|
all users.
|
|
|
|
## Bridge info tab (`feature_bridge_state`)
|
|
|
|
Adds a "Bridge Info" tab to the Room Settings dialog, if a compatible bridge is
|
|
present in the room. The Bridge info tab pulls information from the `m.bridge` state event ([MSC2346](https://github.com/matrix-org/matrix-doc/pull/2346)). Since the feature is based upon a MSC, most
|
|
bridges are not expected to be compatible, and users should not rely on this
|
|
tab as the single source of truth just yet.
|
|
|
|
## Presence indicator in room list (`feature_presence_in_room_list`)
|
|
|
|
This adds a presence indicator in the room list next to DM rooms where the other
|
|
person is online.
|
|
|
|
## Custom themes (`feature_custom_themes`)
|
|
|
|
Custom themes are possible through Element's [theme support](./theming.md), though
|
|
normally these themes need to be defined in the config for Element. This labs flag
|
|
adds an ability for end users to add themes themselves by using a URL to the JSON
|
|
theme definition.
|
|
|
|
For some sample themes, check out [aaronraimist/element-themes](https://github.com/aaronraimist/element-themes).
|
|
|
|
## Message preview tweaks
|
|
|
|
To enable message previews in the left panel for reactions in all rooms, enable `feature_roomlist_preview_reactions_all`.
|
|
|
|
To enable message previews for reactions in DMs only, enable `feature_roomlist_preview_reactions_dms`. This is ignored when it is enabled for all rooms.
|
|
|
|
## Dehydrated devices (`feature_dehydration`)
|
|
|
|
Allows users to receive encrypted messages by creating a device that is stored
|
|
encrypted on the server, as described in [MSC2697](https://github.com/matrix-org/matrix-doc/pull/2697).
|
|
|
|
## Breadcrumbs v2 (`feature_breadcrumbs_v2`)
|
|
|
|
Instead of showing the horizontal list of breadcrumbs under the filter field, the new UX is an interactive context menu
|
|
triggered by the button to the right of the filter field.
|
|
|
|
## Spotlight search (`feature_spotlight`) [In Development]
|
|
|
|
Switches to a new room search experience.
|
|
|
|
## Extensible events rendering (`feature_extensible_events`) [In Development]
|
|
|
|
_Intended for developer use only at the moment._
|
|
|
|
Extensible Events are a [new event format](https://github.com/matrix-org/matrix-doc/pull/1767) which
|
|
supports graceful fallback in unknown event types. Instead of rendering nothing or a blank space, events
|
|
can define a series of other events which represent the event's information but in different ways. The
|
|
base of these fallbacks being text.
|
|
|
|
Turning this flag on indicates that, when possible, the extensible events structure should be parsed on
|
|
supported event types. This should lead to zero perceptual change in the timeline except in cases where
|
|
the sender is using unknown/unrecognised event types.
|
|
|
|
Sending events with extensible events structure is always enabled - this should not affect any downstream
|
|
client.
|
|
|
|
## Right panel stays open (`feature_right_panel_default_open`)
|
|
|
|
This is an experimental default open right panel mode as a quick fix for those
|
|
who prefer to have the right panel open consistently across rooms.
|
|
|
|
If no right panel state is known for the room or it was closed on the last room
|
|
visit, it will default to the room member list. Otherwise, the saved card last
|
|
used in that room is shown.
|
|
|
|
## Live location sharing (`feature_location_share_live`) [In Development]
|
|
|
|
Enables sharing your current location to the timeline, with live updates.
|
|
|
|
## Video rooms (`feature_video_rooms`)
|
|
|
|
Enables support for creating and joining video rooms, which are persistent video chats that users can jump in and out of.
|
|
|
|
## Element Call video rooms (`feature_element_call_video_rooms`) [In Development]
|
|
|
|
Enables support for video rooms that use Element Call rather than Jitsi, and causes the 'New video room' option to create Element Call video rooms rather than Jitsi ones.
|
|
|
|
This flag will not have any effect unless `feature_video_rooms` is also enabled.
|
|
|
|
## New group call experience (`feature_group_calls`) [In Development]
|
|
|
|
This feature allows users to place and join native [MSC3401](https://github.com/matrix-org/matrix-spec-proposals/pull/3401) group calls in compatible rooms, using Element Call.
|
|
|
|
If you're enabling this at the deployment level, you may also want to reference the docs for the `element_call` config section.
|
|
|
|
## Rich text in room topics (`feature_html_topic`) [In Development]
|
|
|
|
Enables rendering of MD / HTML in room topics.
|
|
|
|
## Exploring public spaces (`feature_exploring_public_spaces`)
|
|
|
|
Enables exploring public spaces in the new search dialog. Requires the server to
|
|
have [MSC3827](https://github.com/matrix-org/matrix-spec-proposals/pull/3827) enabled.
|
|
|
|
## Favourite Messages (`feature_favourite_messages`) [In Development]
|
|
|
|
Enables users to bookmark a message or content for a later reference.
|
|
|
|
## Sign in another device by showing a QR code (`feature_qr_signin_reciprocate_show`)
|
|
|
|
Add capability to the session/device manager screens to generate a QR code to sign in another device + set up E2EE. This requires the homeserver to have support for [MSC3882](https://github.com/matrix-org/matrix-spec-proposals/pull/3882) and [MSC3886](https://github.com/matrix-org/matrix-spec-proposals/pull/3886) enabled.
|
|
|
|
## Use the Rust cryptography implementation (`feature_rust_crypto`) [In Development]
|
|
|
|
Configures Element to use a new cryptography implementation based on the [matrix-rust-sdk](https://github.com/matrix-org/matrix-rust-sdk).
|
|
|
|
This setting is (currently) _sticky_ to a user's session: it only takes effect when the user logs in to a new session. Likewise, even after disabling the setting in `config.json`, the Rust implemention will remain in use until users log out.
