Optimizing panel views

As a user, I will keep focus of a panel's content when scrolling inside of another one, that is: the other views should be fixed.

Ideas:

The panels should make use of the max screen size (should be oriented at the different screensizes S, M, L responsisivenes)
The area inside the panel should be scrollable
The scrollbars shouldn't be displayed
By default the Treeview should always focus the actual item selected (which has been chosen by the user; either via knot or via Navbutton)
fix the panel tool icons during scrolling
the knot should open by clicking the title (select property)
