It would be convenient to have the ability to choose parts in the Graphic view that you wish to isolate in the Browser. For instance if you wish to set constraints between PART1 and PART2 you can select them, right-click and pick Isolate In Browser which will then only show PART1 and PART2 in the Browser. That way all the work planes and features are easy to find and next to each other. Right click again to turn off. The color of the tree should be changed so it is obvious this feature is being used.
I get tired of scrolling up and down the tree to find and expand the relevant parts.
