Two or more columns - When u have two or more columns

Even something basic, like a 'column break' property on separators would go a long way toward this feature...

This would be a perfect way of doing it.
Just insert a new item - like spacer - could easily re-position it, would give full control of which item was in each column, and adding one could automatically turn the menu into multi-column without needing any configuration option to do so.

This would do everything I needed perfectly and be a super easy solution.
