Preserving folders tab

I just discovered VibeStreamer and I am really amazed! Thanks for making such an awesome program.

I have one suggestion though. I have a really large music collection, so when I expand my music directory in the "Folders" tab it take a few seconds to load. The problem is that when I switch back to the "Folders" tab from the "Playlists" tab, the directory tree is collapsed and must be reloaded again. Would it be possible for the "Folders" tab to preserve the tree structure after switching back from the "Playlists" tab?
