Yes, I was wondering if it was all out of date.

So actions generally don't receive input signals unless they are a tool or open their own window?

And if they open their own window, can they be fed info programmatically?

Eg: can I write a script that runs the oilpaint filter on the active document with brushsize set to 5 and smooth set to 20 without it opening its own window?

And if I can do that, how do I work out what parameters it needs and how to feed them to it?

Thanks
