Please support swipe to right to go back to roomlist

[agx]

When in a conversation on a narrow display (e.g. on a phone) I have to hit the small button in the top left corner to go back to the room list.

Describe the solution you'd like
Swiping left to right should bring me back to the room list. The button should still be there as it's easier to discover than a gesture.

Describe alternatives you've considered
Alternatives would be to make the button larger but even that wouldn't feel as "natural" as swiping.
