I personally would like to see directories matching as I type. For example, lets say I have this layout in my project:
However, I think it would be extremely useful if while I have typed "cont", if I would see an entry labeled "controller\" being matched. Perhaps by selecting that entry, it could autofill my search param to the full 'controller\' string, so that I can then easily see what is in that directory.
I hope this makes sense. Please feel free to respond with any questions or criticisms.
