In the old Confluence only "Expand " existed and one could nest several "Extend" in itself. This seems to be 1. no longer the case (with tables it doesn´t work also) and 2. there is now in the cloud still recently the macro "Extension". Between the macros "Expand " and "Extension" there seems to be no meaningful difference, unless one of you knows it and can explain it to me? Also will be one of this two macros experied in the future? I think it is a very important makro for long content pages.
