Even better project selector

Hi,
The project selector has already seen some really nice improvements in the past - how about going one step further ?

Since we keep track of all our projects with Projeqtor , we have in my organization a loooong list in the project selector.
For high-level people who need an overview of everything (and for me as administrator), it would be great for these people if we could limit the display, to only keep visible the high-level parent projects in the selector (if the user wants this of course).

We could use the 'wbs' of a project to determine its level in the tree structure hierarchy, and use that to filter out low-level items.

This even high-level users who oversee many projects can use the multiple project selection easily !
