More action IDs to use them with custom secure frames
It would be great to have access to a number (or an unlimited amount) of additional unused action IDs to use them with custom secure frames.
There's a bunch of stuff that can't be done in a secure way without using the type "Action" and an ID (flyout, pet companion, equipmentsets, etc. ... almost everything that goes beyond items, spells and macros to be precise), and all the available action IDs are in use with the default UI.
A way to 'query' if an action ID currently is in use by (aka 'assigned to') a frame would be a great enhancement too.
