Well, you may have a specific requirement for "in-cell" editing, but I
for one recomend "equiation block" editing found in Lotus Improv. The
concept that the cells contain all the information is outdated IMHO.
I know that users are habituated by it, but I also know that the
clearest spreadsheets I have seen were in Improv 2.0.
Oh, just for reference, I worked 3.5 years as pc-network-mainframe
support. Among other things, spreadsheets that had the same formula
in a billion cells was a major problem. With 're-use' in Improv, the
problems simply vanished.
