Colin, I appreciate the advice. I am more a designer than a coder, but I am trying to learn. Learning to customize a few different parts of an existing strong code seems like a good way to learn. Pixidou was a good example of someone taking your tools and making a nice interface. I was just wondering if you had seen someone else do something like that, with some of the other variables you built. If not, that's fine, but examples are easier to learn from. It'll be nice when I've grown enough to know what it all means and be able to write my own code, but I do envy your excellent skills. Well done and thank you again!
