Since we now can change the amount of boxes in the pc, I think it would be handy with the possibelity of going upwards/downwards 5 or more boxes at a time :) I personly play with 80 boxes, and it can be quite a pain sometimes to move 30 boxes to find a pokemon XD
An ability of searching for a pokemon in your own PC would be amazing as well :)
A last thing is that it would be amazing if you could name the boxes just like in the games :)
