Search: Overlap fixes

[OlofSvahnVbg]

There is some issue with the overlap of the search window in app:

As shown above, the search result window under the search bar is always displayed on top, which is not ideal when working with one or more control windows placed to the right of the screen.

This has been reported by some users as a problem.

The drawerButtons have a similiar problem when overlapping with other windows:

Otherwise, the control windows behave correctly when interacting with each other. The active window is put on top when clicked or interacted with, as it should.

I think this should be fixed by changing logic for search and drawerbuttons.

It's good to see that this long-standing issue is being brought up.

I think that the logic must go into a few places, notably:

• BaseWindowPlugin that controls all plugins with draggable windows
• Search (to determine if search bar and its autocomplete should (temporarily?) overlap all draggable windows)

(There might be other cases I’ve overlooked at the moment, as I’m writing off the top of my head.)

Drawer toggle buttons should perhaps just stay "below" on all occasions. I mean: this screenshot clearly illustrates the lack of consistency:

Does this mean that a global controller is needed? I don't know. I guess we'll see how things turn out during the implementation phase.

So I changed the issue a bit. As mentioned above I think changing logic for search and drawerbuttons is enough for now.
