I have avoided learning to much about TweakUI since tweaking frequently can lead to instability. This is a throwback to my Win98/Win95 days. I finally succumbed to tweaking my Local Places since the default locations were not much help. I left in Desktop, My Documents, and My Computer but I added Favorites and Downloads. Downloads is a network directory I use to store all my downloads. I could get to it via Favorites but since I use Downloads a lot I opted to save a click.
