Minor game additions you would enjoy

>Nursery doesn't automatically say bye when you don't wan to take back the other pokemon

That thing like in prism where you play as your Pokémon.

>Trainers have a set of different idle animations based on the current battles outcome (ie worried, smug, on a roll/sweeping, brickwalled, etc)

Your Pokemon or the Trainer does a victory pose after trainer defeat

Starters from other regions becoming standard encounters
Island Scan is close to that though
