Gwenview window takes too much vertical space when editing tools are shown

Currently, showing the editing tools makes the window have a minimum height which isn't small, especially on a screen with below Full HD resolution. 
Look how it takes the entire screen height on a 1366*768 screen in the attached video.
I suggest the items in the editing tools panel be made scroll-able, so the window can be resized to a smaller window height and take less vertical space. I feel it'll enhance the experience, especially on lower res screens.
