May I suggest something else? Not exactly an icon representing the
actual item but a symbol so we know the Pokemon holds an item. Less
coding, not many new mini sprites, blah blah.
@BlueAbsol
(about the mini symbols) I suggested this 1st and it didn't got
much support so i changed the post....
I suggested to add a everstone and a pokeball. everstone cuz a lot
pokemon hold it if you try to complete the dex or you don't want to
evolve them etc and the pokeball for all other items..
Support! I like BlueAbsol's idea more, a lot less to code and it's
not necessary to know which item is holding, you can click the
pokemon and know what item is.
