[Feature request] Support "@run-at context-menu" or some other way to make a script on-demand-only

[not-holar]

@run-at context-menu doesn't seem to be supported.
The script is instead reported as having run-at document-idle

Since scripts can be run manually, it would be useful to be able to disable a script's automatic execution for those which are only needed sometimes.

I have used GM.registerMenuCommand for script functions which should only be executed on demand. Functions registered that way are available in the "Script Commands" submenu at the bottom of the Firemonkey popup menu. Would this work for you?

Note that you need to @grant GM.registerMenuCommand in the script header for this to work. See the Firemonkey help page for more information.
