Like creating properties where there is a description tab to write integer range or a short desc. This would be handy with variables as well such as mentioning what gameplay mechanic it is attached to or whether it is a global variable etc.
Even though often one names the variable to be descriptive sometimes when doing something complex it helps to be able to make a note to self for future reference when adding new content or fixing a game after a long break from it.
