I would like to be able to organize large case structures to speed up code reading. I find that when case structures from (10+ cases) it takes a long time find the case I am looking for. Adding menu separators (i.e. no associated case only cosmetic) would allow the programmer to organize long case structures into groups. I would expect this to be added and removed using the case reorder GUI.
This is only to improve readability of case structures and has no other purpose.
