Well, if you look at Karbon (or Photoshop) you see a listview that shows all 
actions. Each action can be enabled and disabled individually. That's what we 
need. And for this tool we need to have a clear separation between the data 
as it was when the action started, and the data as it will be when the action 
is stopped (this might be useful when we want to implement gradiented or 
otherwise effected strokes, too). I.e, during the action you need to have 
access to the data as it was when the action started. Designing something 
clear and comprehensible that offers that with a good API and a 
memory-efficient implementation is, as Bart said, a challenge.
