I'd like to suggest a slight improvment for the frame tool. Currently, the frame tool preview shows that you can use this tool to create a shape if there is one to create by simply dragging it over a shape and creating one. However, this doesn't seem to be the case. I'd like to see if it could be made to act like the preview window. Maybe act like the magic wand tool or even the lasso tool. Otherwise, the tool seems to be a shortcut to clipping masks using shapes.
It would shave so much time if it worked like the preview shown. It blew my mind until I attemped to use it. It took me a while to figure it out, but I am still excited at the prospect. Keep up the good work!
