It would be nice to have the ability to lock elements in place. Often I find that when dealing with small elements or thin text, it is difficult to click on it "just right". And, if you don't notice, you can inadvertently move a background element. I realize that I can undo the move, but it's rather annoying to have to use undo so often. Also, it would be nice to re-add the ability to save in a higher resolution back into the program.
