I like the third option.Question: About the multi selection, would you prefer:
- Something like the official multi selection, where you draw a rectangle and move the selected rectangle to an empty area. (transfer will be cancelled if the empty area is not enough, but the selection will be kept)
- Something like the official multi selection, where you draw a rectangle and move the selected rectangle to an area, which will result into a swap for each Pokémon present in this area and the original selected rectangle.
- Something like the Windows file/folder multi selection, where you "check" some Pokémon and when you are done, you press a button to move each checked Pokémon to the current box (transfer will be cancelled if the empty area is not enough, but the selection will be kept).
