Using Liftoff right now and so far looks like the best. At the very least, the most mature.

With that said, a few things in mind:

• Long pressing a comment suppresses it, but tapping does nothing. The tap action could be used to suppress (what long press does now) and long press should show action buttons for the comment (that should be hidden as default)
• When searching for a community, sort by number of subscribers or active subscribers or number of posts. It seems to be random now, maybe? Maybe alphabetical order? Can't recall, but prioritizing larger/more active communities is a good thing and concentrates things a bit more. (For example, search for "movies" on Jerboa and you'll see the largest community that your account can see first and go from there. But on Liftoff, the first results aren't that relevant). Also, show number of users/posts as in other apps in the community search page.
• "Go to post" button doesn't work. It fails to load (yours or anyone's)
• Pressing "back" button should open a popup to confirm if I want to exit the app instead of a banner asking to press again to exit. Just QOL.
• Communities tab doesn't show my subscriptions correctly? Don't know if there's a problem in Lemmy itself, tho, but I'm subscribed to some communities that aren't showing up there and some that I'm subscribed to are duplicated. Looks to be a problem with communities with the same name, but in different instances. I can correctly see the communities if clicking them through "about", but not from "communities", as I'm taken to the same place, no matter which I click.
