I updated this plugin's version for the time being, which besides an option to add as you create it, includes a couple of bugs that could potentially crash your testplay.
Didn't see the crash you reported, I'll keep looking for it, but it would help a lot if you sent me a log report, like the one you sent with VisuStella plugins on.
Since we didn't get to a specific solution, I begun to make the simplifier plugin. I'd say I'm nearly 80% done. It would let you run the commands from the other two (and other related if I make them), without having to manage the data manually, other than the actorId you want to create or delete.
