Swipe back to the latest channel in mobile app

Problem

Currently, you can swipe from the messages back to the channel list in the mobile app, and then back again from that list. But it isn't possible to go back to the latest channel you opened if switching community. (example : you are on the DM page, click on fluxer HQ, and then can't swipe to get back to fluxer-discussions)

Proposal

My suggestion is to implement the same swipe gesture as it currently available to go back to a channel you swiped out of, for going back to whatever the latest channel you opened on a specific community was. I think this could also be triggered by pressing the community icon twice, like the discord app currently allows you to do.

Notes

The swipe gesture is already available, but adding this feature would require the app to remember what the latest channel you opened for each community was.
