This is very small things.
1. That when you move a stack of items you move them as stacks, not as single pieces of the stack. I can’t think of a single reason when you want to unstack stacked items.
2. That in the shop for selling stuff, things you have at home doesn’t show up AND if you have several of an item, they show a number behind them on how many of that item you have.
Right now the selling in the shop is VERY cluttered.
3. If you have something selected in the shop, either for sell or buy, and then click buy or sell, it should stay selected, instead of removing the selection completely. If you sold/bought last of that item, then it should have same relative positioning. Also this apply to trainers as well.
This is small things, but they are very annoying, and if you fix those it will improve the overall feel of the game. Perfection is in the small details. Oh and great game, I really love it.
