I stumbled across the NSUserDefaults (omz had used it for the theme editor) and noticed editor actions are there. Here is a set of utilities for adding or removing editor actions, programatically. (for instance, i am going to put in a pull request for stash to self install an editor action).
especially useful since deleting an action through the menu seems to crash on my device anyway. Also, since you cannot tell the path from the action menu, this lets you check which copy of a script you are using.
