It has come to my observation that, filling your pc boxes in pixelmon mod is very easy, especcialy when youre on the server i play on with Auction House and so many breeders.
So what i want to suggest is a auto sorting feauture wich makes it so much easier to sort your pc and find the pokemons u want.
As a staff i often hear people missing a pokemon or not finding it in their pcs, and its often because their pc is very unorganized and they have issues finding them.
How they can be sorted you may ask.
Well the first and most obvious is Dex numbers so page number one pokemon would be bulbasaur then ivysaur then venusaur and so on and so on.
Second option could be after type, wich would make type specific tournaments or gym battles easier, for example Normal then fighting and so on.
Third option:
well this might be an odd one but levels, yes i think it could be a good idea to include level sorting so you can check your most powerful ones and sicard the weaker ones but thats a one i see very little use of.
Final one:
Ivs/evs I think this would a breeders dream for sorting, and for commoners who just want to find their strongest pokemons, although i see this as server side sorting and not singleplayer.
(Additional)
Nature sorting, sorting after natures so like admant, Brave and so on.
Thanks for reading much appreciated.
