Been out of town and just got a look at the latest version. You guys did alot of work on this since the last one. The object wrapper was a good idea. I did have a couple of issues with my shell extensions, but that was a fault on my end with the license system I use and was easily corrected. I only allowed them to work in certain environments.
I wouldn't mind having a single property to always show the file extension regardless of the setting in explorer and possibly a before tooltip is displayed event of some type, so I can display some custom properties a bit easier in the tooltip. Might be there already and just missed it.
