I have been trying to wade through some old Action manager Code to see if I could bring it into a new UXP Plugin for Photoshop.
After doing some research, I stumbled across this Script which cleans up the AM code and presents it into something more readable i found.
With nothing to lose, I installed it and so far its cleaned up quite a bit of my older AM code and from the output I have managed to convert it into a BatchPlay function.
Here is a link to the Tool if anyone is interested.
