Reduce space in right-handside menus

[stoecker]

Currently the menus in the right side use a lot of space and it is sometimes hard to see the relevant content. I think howto fix this for a while now and I think I found a solution below.

Nearly all of these follow the structure of a data display and a button row below. Now the button row is not really necessary most of the time. So a great improvement would be, when this buttons are displayed only when needed.

Idea:

• Allow to separate the display part and the buttons in ToggleDialog.
• Find a possibility to activate the buttons only when needed (make configurable!)
  • Display when mouse is over the relevant menu section
  • Slightly expand the display, so the buttons find enough space for display

We could step-by step update the ToggleDialogs, so this new features needs not break plugins.
