The TMS diagramming components are actually very high on the list of
components to use if I have to build this myself. If you already had that
capability, I would probably already have bought it. The question at this
point is how long it would take you to have it ready. :)

What I would like to see is the ability for an end user to design a script
visually, and have the resulting script be serializable.

>From a technical standpoint, it would seem like the developer would have to
supply actions to the script as things that user can actually do. These
could be TAction descendants, or just any class implementing IScriptAction
(I perfer the interface approach, personally). There would also be
decisions that would have to be made, perhaps the same pattern could work.
Basically, the trick here is how the script interacts with the host
application, aka how the host application is exposed through the script.

Another issue would be how the diagram component would interact with the
script. Going from a script to a diagram should be a piece of cake:
MyDiagram.LoadScript(MyScript). It would also be ideal if you could do
MyDiagram.GetScriptObject: TScriptObject as well, although I can see a lot
of potential difficulty in that.

Just some random thoughts....
