I want to re-order by user groups by a custom business logic (so not by group title). How can I achieve this? The Joomla interface seems to provide no option to do that.
In the database, user groups are stored as a nested ordered set (so with lft/rgt) columns. I'd rather not set all values by hand, since I have about 30 user groups, with complex hierarchy.
Can I activate something in Joomla/Admin template that will allow me to re-order the user groups? Even with the old and boring "move up", "move down" functionality.
