Along the lines of draggable patches, here's a patch which lets you drag jit.windows by clicking anywhere in them, so it lets you have a title-bar-less jit.window and still be able to move it. You can turn the border on to resize it, then off to have it be just the image or movie.
The dragging doesn't "track" as well as using the title bar, especially with a movie playing, but it works... drag from the middle for best results. Also, when you go fullscreen, the dragging is disabled.
It's been really handy while developing patches---you can get it out of the way a lot quicker than using the title bar, which helps a lot if you use floating windows that always seem to be in the way...
