I've looked at Acron calc. It does have a nice menu, but like with other similar things, while having have the right idea it does not take it far enough. In it keyboard is keyboard and menu is menu, they are separate. In my project keyboard is menu and menu is keyboard.

I already noticed that. My original intention was to scroll the obstructed cell into a viewing area when keyboard pops up, but then I noticed that it is nice to have a full view of a number. The number in a cell may be tightly formatted to fit, so there may be a benefit of having attached indicator. Maybe even with full stack display, while we are at it.

Nice. I never heard of this project, thanks. It does look a little bit like it, with spreadsheet-like property sheets. But again, see, how xpand wastes screen space? Menu on top, menu on bottom, toolbar -- my idea is to turn it all into a keyboard/menu hybrid. Scrollbars are a waste too -- swipe-scroll is the way to do things these days. But, I guess, that was not apparent at the time.
