TabsInSpreadsheets

You asked :-)

Spreadsheet tabs introduce a new, ad hoc & unnecessary mechanism for something that would be handled better and with more principle by a more general mechanism.

\1

Namely

1) tabs are part of the EDITOR, not the DATA & should be late bound to their content.Think of browser tabs. Or panels in Emacs.

2) we should have a way of storing multiple DOCUMENTS within one ARCHIVE file. \2

3) documents (including spreadsheets) should be able to refer to / transclude from other documents.

If you have 1, 2 & 3, you have something more flexible and you don't need tabs within spreadsheets which is just fudge for lack of them. \end
