even on my tiny laptop screen i dont have much of an issue with one or two interface boxes being open. you know you can drag them around to the side of the screen where they're less in the way?
generally if i'm somewhere where i'm throwing a lot of balls i have it covering the top half of chat to save even more space, and you can always press ctrl if you're heading that direction and need to move the bag box to the other side.
number keys 1-6 used to be used to send out and recall the poke in that slot but now it's for selecting which poke to be controlled with right-click, i dont see much in the way of options to have both implemented that'd work for everyone :/
