First of all congratulations for a very useful program & well done for making it widely available. After testing shortly, I have three comments:
1- using Control Q in the floating windows to go one level deeper does not "feel" logical. Why not just make it with double click?
2- To make it very useful for documenting formulas, consider having the option to "record" your steps, which creates a new sheet with Element, location, value and formula in colomns.
3- Within the 2007 ribbon/menu, give the option/integrate into the menu to explore active cell and go to last explored cell using the mouse. Not everybody prefers short cut keys.
Thanks again!
Arjen
