Change folder tree display format?

I'm changing some of the colors of the files and folder items using Preferences, Display, Colors & Fonts.

Is it possible to change the folder tree display parameters? For instance, I'd like to better highlight which folder I'm in when the folder in the tree is not selected... when i select a folder, it's highlighted with white text on a dark blue background. If I then highlight a file in the Files pane, the folder in the tree reverts to black text on a very opaque background. I'd like to color that up a bit.

Thanks.[/b]

While you can change the main text and background colour of the tree it looks like the selection colours (with and without the input focus) are always the system-wide ones (from the Display control panel).

(I've moved this over to Feature Requests.)
