I am working on screen shots of an application, that uses the full screen size.
I also measure the font size, so I need the 100% zoom.
I have minimized the bottom panel and also hidden the scanner toolbar.
But I need the thumbnail panel to select different screen shots (need to read the file name, select it, modify the screen shot, go to the next screen, compare, edit and so on).
So it really would be very useful if I can un-dock the thumbnail panel (this way I can move it to the second monitor).
Same for the toolbar on the right side (including the zoom slider).
Alternatively you can add [F11] hotkey for full screen mode (like Mozilla Firefox has it).
