Hey, sorting will work across all boxes after the next client-server-update.
Filters will be usable within the search bar.

That's not possible yet, but I'm working on making it so you can drag and drop a Pokémon between two others. This way, you’ll be able to move a Pokémon forward in your box without having to shift all the others manually. Hopefully, this will be included in the next update.
I'll mark this post as implemented and lock it. For any remaining suggestions, I recommend creating a new post.
