Version 2 has a few tweaks. Still to do - make a play all option and clean up the code.

I haven't looked at all the code, but why is Controls a class? There's no state it encapsulates that the methods share. Couldn't those methods just be functions inside a module instead?

yes. I'm just playing around with classes. It's even easier getting the code to work if it's just a function or methods in the same class.

Just try and use classes appropriately - they aren't always the right way to group related functionality, as in this case. I'm not sure what you mean by "easier to get the code to work" by using a class there. The functions are completely independent of one another, so if they were in a module, you'd just have to import them and use them.
