I’m in the same camp as some of the other posters here so far.
Some very immediate suggestions that I have after opening the app for just a minute would be:
-The option of “all inboxes” for folks with multiple accounts
-a swipe from the very left edge of the screen should bring up the left nav menu, like in the gmail app, while swiping from the non-edge section should bring up the actions like it currently does.
-along those lines, 2 different levels of actions per swipe (left short, left long, right short, right long) would be great and let us add more swipe actions. Many apps do this successfully. The swipe actions are currently far to large of a movement before actually being triggered. See Apollo for Reddit, at least on iOS, for examples of this. I don’t think people need the swipe to hover there if their action didn’t swipe deep enough anymore, as this gesture is now commonplace. An “undo” action for a few seconds would be very helpful as well since on mobile we more often make mistakes. See gmail app for example.
-It would be great to show the icon of the current account at the top (where your current search icon is) so we can tell which account we are in without tapping on the hamburger menu. And, a swipe down on that account icon should change between accounts. All of this is implemented in the current gmail official app on iOS. The search just moves to the empty space in the middle of that top bar.
Some of these things may already be coming in the settings button that we don’t currently have on iOS, so I apologize if they are already being worked on.
I’m really looking forward to being able to use this app as a daily driver!
