It would be nice if you could add some fine zoom control shortcuts or tool. Right now the zoom steps are fairly large, which is fine for standard use. The large zoom steps can make saving screenshots difficult because or the level at which analyzer information is displayed can vary. I noticed the Up/Down zoom step shortcut and the Ctrl-Up/Down large step shortcut already existed, but an Alt-Up/Down could be easily added. It would be nice to have a mouse shortcut along with the keyboard command.
