A way to get all TMs listed from the wiki without randomized mode (Especially TM102 and TM103 cos ampharoom is slow and toxic spikes are better than toxic)
More Kalosian and Alolan pokemon
Fixing bugs with going through walls, lacking some move tutors moves' aviability and sprites moving somewhere or stucking on the screeen.
Gimmicks - mega and z-moves
And removing
Possibility to softlock yourself (even though debugger exists, the less bugs the better the game is)
P.S. pokemon infinite fusion is my favourite game
