Could you make the text columns in the tree pane sort naturally, ie not 1,10,11,12,...,2,20,21, etc? This seems small, but it's huge if you routinely mix text and numbers. (I can't believe Excel still does not have this! I had to write my own vba routine to do it.)

Suggestion: Natural Sorting
Awesome! Here is an article I found on the subject while writing the Excel routine. I didnt use hash tables (I'm not a programmer!), but it's an interesting look at different methods.
