When I'm editing ui layouts with the QtDesigner, I rely very much on the object tree (right side) to check if my widget hierachies are fine.

When I select a widget in the layouting frame, the object tree changes to the inactive palette. Now it's almost impossible to see which widget is highlighted in the tree and I can't see where my selected widget is in the hierachy.
See screenshot: the highlighting of "verticalLayout_2" is almost indistinguishable from the alternating row-colors.

To see what's selected in the tree, you have to click the tree (change focus) first which results in a terrible workflow.

If you can always keep the active palette for the object tree, it would be much nicer to work with it.
