MS Excel, WPS Spreadsheets, FreeOffice PlanMaker all their tabbed interface have Formula tab while Calc now show some Formula related commands in the Tools tab. My suggestion is to move them to a new dedicated Formula tab. Hopefully we have some nice grouped Functions also. Otherwise we may use basic function list like in the Calc sidebar.
Here the list of Formula command related tab:
Show Formula (not sure it should be in View tab or Formula tab but WPS and MS Excel shows it in Formula tab while FreeOffice shows it in View tab)
Sounds like a plan. Interested, Andreas?
