Oh, it is, many missing features, several come to mind: no way to mark anything as read, not even notifications, you can't open the profile of a commenter, no saving images...
But the UI is pretty, you can already save, vote, and reply to stuff, and development is active. But clearly there's good reason for the app to only be on github for now. It's my favorite so far in terms of UX.
Yes! So much this. I've jumped ship and started using another app called liftoff. It's got bugs because it's just as new as all the other apps around right now but it works with the current version and I like it. Might not go back but it's nice to have options
