Unfortunately no one on our team has much experience with writing scripts for After Effects. Writing scripts for Photoshop has been absolutely terrible, so it's hard to gather enough motivation to jump back into more of that kind of pain. Still I know it would be useful and I've wanted us to work on an AE script for a long time, but there always seems to be more pressing issues that need our attention.
It may be that the current script (which was contributed by another user) can be salvaged. Do you have any information on what doesn't work about it?
