The most common question I get through all channels is "does it show thumbnails in the folder?", which admittedly would be a nice feature to add.
I'm creating this issue to track how many requests I get for this feature, and gather together any bits of helpful code or documentation related to Windows shell extensions.
So far I have a total of 8 direct or indirect requests for a thumbnail feature that I can find.
The required COM object probably needs to implement ExtractImage2, and according to one email I received, the GUID for the shell's thumbnail extractor is {BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}. (That email from 12/23/08 also includes an example application for shell icon integration and an installer that sets up the proper registry entries for either Vista or XP - need to extract that info and add it here)
