Show the project directory in the palette panel

It would be really useful to have the current project’s folder automatically show up in the palette so you could easily drag in files.
You can currently force things to show up in there by using NTFS junctions to add links to other folders, which the palette recognizes. But if you have lots of projects, it would be less convenient to have to sift through a long list to find a file that’s right next to the current .toe.
It would likely need to involve more automatic refreshes though. Currently it seems that the palette needs to be manually refreshed to detect changes.
