These icons are based on Feather as the original source, but they have various
tweaks applied, such as stroke width, color, etc. Hopefully the tweaked name
makes this more obvious in the future.
make mx_fadable not do anything anymore, and make room settings
full size.
Room settings haven't been designed yet, so all of this will
have a full pass when we have a go at it.
make room name take as much space as it needs (but not more than width)
put all items apart from right buttons in one flex container
so name and topic can grow as required
more small tweaks
