I even dont know what you call that button. but whatever
With this button you will be able to move in any sub folder of the project easier without losing the focus (selected object) of inspector view!!

it will be more usefull when dragging an asset to the inspector, instead of locking inspector to drag then unlocking inspector...

for us that would increase our productivity by about 15% cause most of our work is done(modelling, data structing, animating, level design) are done in unity, not in external application.

so it would be a great to see this at a next update..
