I've been using the new gallery app for the oneui beta and they've made it so when you scroll down it hides the bottom bar which is so annoying, it's not helpful and you have to scroll up to make it pop back up which is an extra step. Then the albums page has the same sort of stuff, only shows certain albums and if you want to see allmof them you have to press a button to view all, so not helpful.
I really hope these don't make it into the final product, they're just annoying.
