Impossible to navigate files in tree mode

Since the 1.9.2 update, the tree view in the "File Status" view has completely disappeared. This makes it really not easy to find a file in the list of all files, say to look at History of a file, or any other action you would want to do on a file that is not currently being modified. In complex hierarchies of files, looking at the whole list of files in a flat view is a real nightmare.
