I noticed that Box does not have a high-level folder tree view, except in the 'All Files' page (you click on the arrow next to "All Files"). Many Box folders in my company's folder structure take a very long time to load - however the folder tree view on the 'All Files' page loads quicker, but still not as fast as another application like eBuilder. Having a permanent option on the web application would be very efficient when tracking down files, and load times won't be as cumbersome. Currently, having to click through multiple folders in order to access the contents of a folder that is buried deep within another folder is very slow.
