Sometimes, I find it tedious to have to click back on a secection tool again just to get rid of the secection I have. Say, I made the selection, moved it, then I have to click back on one of the secection tools before I can continue editing the entire image. perhaps, from the arrows at least, when you click off of the selected portion, the selection dissappears (not erase whats inside, but the physical selection itself, limiting what you edit).
