Great update! Thanks so much for bringing back compact mode for posts. You knocked it out of the park, and I think it is pretty perfect the way that it is now with respect to text size, information density, content layout, etc.
I think it would be great to see a compact mode for comments as well, that would change things like text size, content layout (one line for username, timestamp, vote counts instead of two), hiding certain elements (save, reply) etc. I’m not sure if you have anything in your upcoming customization update for that. :)
Edit: Also, I’m not sure if you are aware, but the options for All/Subscribed/Local that you get when you long press on the Mlem app icon do not seem to work. When selected, the app opens, but that is it.
FWIW, the app developer name did used to be “Gavin Casdorph”, and now it is “Culivio LLC”. Obviously the reason for the change is probably innocuous, but OP is not making that part up.
