Standard window: add option to display files as tree structure

Currently, files in the Local Files and History views are shown as list. The user only has the option whether to show it as name (path) or path/name. Depending on the directory structure the path part can get quite wide which might cause issues in the History view:

Alternatively, there could be an option to show the files as tree-like list adding directory entries for each parent directory (without a way to collapse directories):

This might require less horizontal space (but a lot more vertical space).
