I've written exactly this kind of thing (on more than
one occasion, I think). But I always get half finished
and then I'm distracted by something seemingly more
important. But I use my LinkedList object to store
the commands. I even had a "command editor" working,
where you could add or delete commands, move them
around, etc.

Perhaps between us we have more or less a complete
solution. :-)

Cheers,

David
