One of the problems with the layout and systems-on-a-page and 
measures-on-a-system is that the different kinds of info is linked very 
weak. There is no "ownership" here (a page doesn't own its systems, and 
the system doesn't own its measures). The relationship is all done by 
Finale's layout calculation, and then the programmer have to scan for 
the relationships.

I'll see if I can simplify some of it.

Btw, the way scripts are set up in groups will be expanded in the 
future, and that enhancement will affect group scripts as well.

Right now in JW Lua, a script is "static" and it behaves very much like 
a plug-in. In the future, the user will be able to set parameters for 
the script (when the script is set up in the Manager). That way, the 
user can have multiple instances of the script available in the 
Explorer, all with different parameters.

That addition will make it possible to make group scripts that behaves 
almost identical to "Actions" in Photoshop.
