The Poke Pager was a good idea. Now make it so you can select which of the pokemon you own should be paged
Full character customization
Character classes that give small perks
Following Pokemon - feel free to exclude those too big to make sense.
Option to have any small pokemon sit on your shoulder
Berry planting where you don't literally have to plant, mulch and water every 80 individual plants!
Remove all off-game stuff like Festival Plaza and integrate them more into the regular game world
Difficulty setting. Hard mode means more pokemon per trainer (all gym leaders and E4 has 6!), full movesets and actual AI strategies
An actual Nuzlocke setting. It's a little bit tedious to remember all the self-imposed rules. Especially between saves
Gradually start putting old mythical pokemon in the regular game like Deoxys
Some mythical/legendary gets a quest line unlocked after certain achievements (beat E4 X times, get Y rank in Battle tower, own full dex... or what ever). Stuff that's hard, but not impossible
New starter types. I don't give a damn if they are internally balanced. Just something new instead of water/fire/grass
Vastly larger region. It's the goddamn Switch! At least 4x the size of current regions. No games ever really use the final ~40 levels anyways
Remove roadblocks - If you want to go into the level 50 area with your Caterpie, go for it!
