Ok I found under the mission folder you can use sub folders and still show up in editor. It will start from the first sub folder and alphabetically sort it then go to next folder. Folders wont show up in Editor but you can control what comes up first or move sub folders from the editor list to shorten list. O yes you can remove a folder and do not have to restart editor. Just click on MCU or something a reclick on groups and the list will readjust what you present have.
Added the pic of 2nd folder to see how it put it in order.
