Thanks so much for your thoughts and ideas.
Yep it's true the current system isn't very flexible and can be time consuming. We'll be addressing this as we go but we're taking small steps with the scripting because one thing we're very aware of is not everyone wants to be a programmer, though I wish they would :) So we need to make sure the base system can be used for all situations without getting too complex. That said we have a lot of demand for ideas like your suggesting so we need to make sure these features are available, but not required. Hopefully you'll see this development unfold in future releases.
Thanks!
