I have my window manager manage the windows. I can use all my usual keys and shortcuts to modify/move/alter the windows. Eg mousescrolling over a window's title bar to reduce it to just its titlebar if I do not need it (there is a shortcut too, I forgot it though). Being able to make windows always in front. Being able to have multiple images open and move/resize them with alt+(left|right) mousedrag.
