Firstly I want to mention this is a really great idea and very well implemented. Will be a real timesaver for me as I'm too lazy to organize my start menu and am mostly using WIN+E to launch a new instance of Windows Explorer and navigate by keyboard to what I wanted to launch.
A small bug I've noticed in version 1.07.21 (sorry if it was mentioned before, I couldn't find it using the forum search):
When you add a search folder ending with a backslash, e.g. "D:\", and have 'Result Label Path' set to 'relative to search', the first character of the directories is always missing in the result list - e.g. I get a result "opera.exe" located in "pera" (instead of "Opera").
Suggested solution: Find and Run Robot should drop a trailing backslash when I'm adding a new search folder.
