It would be convenient for Whisker Menu to include an option, when right-clicking on a menu item, to edit that item via exo-desktop-item-edit. This functionality would be similar to right-clicking an item in XFCE's standard application menu. While Whisker Menu does offer a configurable shortcut to a menu editing application, this is, at least for myself, rather inconvenient for trivial changes, and some users may not have one installed.
