Column and Row Groups with Expand & Collapse (+/-) like in MS Excel
In MS Excel you can easily create column and row groups by just marking the respective area. Then you have [+]/[-] buttons outside the grid to expand & collapse these groups.
It would be great to have this functionality also in Jedox Excel.
Especially if you have a lot of those groups, it is more user friendly and better maintainable than adding a lot of "free-flow buttons"+HIDEROW/HIDECOLUMN formulas onto the sheet.
One level would be enough at first..multiple levels would be nice-to-have.
