Automatically expand tree view side pane when user descends into a directory in main pane
This may be already working for others and not me for some reason, or this could be intentional by design.
When the user has the side tree pane enabled, when they click on a folder in the main pane and continue descending the side pane does not expand the tree down to the currently explored folder.
For example if my home directory "Me" is the root in the side tree pane and its contents listed in the main pane, when I double click on the "Documents" folder within the home directory, and then again within its child "Stuff" folder, I would have expected the side tree pane to have expanded these two folders. This is the default behaviour on a number of file managers already.
