I agree entirely.
My frequent request to MemRise was to give Contributors all the editing rights of the Creator (except deleting a course, which they stated but did not grant in practice), and the reordering of columns, like a spreadsheet.
The reordering of columns may not be important here, but was on MemRise, as the first Attribute column was the only one that showed at or after testing - a nice feature.
