Development of a spreadsheet may rely upon conditional formatting, sometimes heavily.
Similar to range names listing one can get through the Insert > Named range or expression > Paste all UI, another enhancement would be the possibility to get a conditional formatting summary, inserted starting at the currently active cell.
This would immensely help documenting the spreadsheets and their maintenance.
Sounds like a perfect task for an extension but nothing that needs to be built directly into LibreOffice.
Discussed with Markus and he was referring to it being a 3rd party extension, so I am closing this.
Jean-Francois: you are advised to contract some 3rd party to develop it as an extension.
