Im not familiar with coding, but maybe just make the PC 1 storage, with a slidebar on the side so u can slide down, maybe have the ability to mark some pokemon as "favorite" or "PvP" and have a filter option for that, also if all are in 1 Box the sorting after Name/Lvl would actually make sense since for now sorting after name and then looking at B for Bidoof just shows the Bidoof in PC1 and not the one in PC3... Alot of QOL changes possible here to have the players manage their pokes better
