Hermann Schinagl has a great shell extension that provides oodles of functionality around junctions.
I have a similar extension, but while mine is more of a "visual cue" sort of thing, his actually
does something. I dropped him a note, and he just integrated my icon overlay, and I'm gathering that he's going to put the property sheet in, too, when he gets time.
[UPDATE: As of March 26, 2007, Hermann has integrated the property sheet into his extension. Woohoo!]
Check this thing out - it's the bomb. Plus, once he's got the property sheet in there, it totally obsoletes mine. (Of course, I offer the source code to mine, so for those wanting to learn a little,
go check that out.)
