I generally don't have much use for spreadsheets, but the interface to this program is quite stylish. I'm a stickler for good grammar, however, and the non-capitalization of certain menu items is a little bothersome :-) (nitpick). The extensions to GadTools look excellent and offer a very intuitive environment.
This beta Guru'd on startup my OS4 box (800000003), but after hitting Continue in the Grim Reaper, everything was fine.
I'll try it in place of clunky old TurboCalc next time I need a spreadsheet and see how it holds up. Hope to see more of this project soon.
