Currently the selection of multiple objects is a pain in the ass. If you have one room made up by a box with transparen color as second color and you select multiple objects inside it most of the time the outer room is selected as well. This means if you want to delete 3 tokens inside of a room, you will delete the room. I suggest that selection ignores transparent pixels. The exact same is true for polygons. With this improvement of multiple selection we also need the possibility to edit fields for multiple objects at once. It should be obvious for how many cases this is helpful: Set "all players see light" for multiple tokens, give control to players for multiple tokens at once. Multiple edits should be very easy to implement as it does nothing different than iterating over all selected objects and only applying changes the user made, keeping the unique old value for all other fields.
