How about supporting functions like ABS as EXP in a better way than just as a function name.

Hi,

All brilliant ideas, I can implement some of these very quickly.

Regarding the Sum and Product examples, what would you suggest we do for:

=SUM(B10:C20)

As for Google Docs. Yes you can use the URL, however what you're linking to is on our test server, so once we finalise the Excel Addin (which should have been done ages ago, except for other work thats bogging us down!), this URL will officially change. The test url will stay, but I can never guarantee that it'll work always. Nevertheless you are free to use in in Google Docs etc; though we would off course appreciate (but don't insist on it) an acknowledgment in anything you publish.
