More fluid script options within macros...

Ability to add an action that is just a black slate for javascript code. That way if the macro already has functional pre-existing actions and macros in it, you don't have to convert the whole thing to a script. Just insert the manual scripting that's needed.

Ability to "convert to script" on a singular action within a macro (similar to above).

Ability to pull all the source code from the actions/ macros currently involved in the macro you're working on. In other words, if a macro pulls in other commands using "command ID", it would be great if "convert to script" or some sort of "copy as java script" option would pull all the source code instead of simply referring to the command ID.
