In every other program on the web, if you LEFT CLICK and grab an edge of the frame - it should maintain the aspect ratio (at least that's the way it is in just about every other paint or edit program in the world). But here you have to select 4:3 ot 16:9 (which is also not in a dropdown menu instead of the main menu - just one more step to go through). Then you have to CLICK maintain aspect ration. Why not just do what everyone else does and make it so that when we LEFT CLICK and grab the edge it automatically maintains the aspect ratio???
