Don't know where to add this as I'm not sure it's a plugin.

My use case.  Often I'm using the "script console" to run debug code or doing investigations.    To build the code I'm storing in note pads and such everywhere, which doesn't help the shared admins at all.    

If we had a history of last run scripts that would be one benefit.

Ability to "save" the script and have it retrievable in a select list, would be another option.
