How can I get more code?

I love this plugin. Is there a version I can purchase that allows me to create more codes? 15-20 would be nice.

I’d also really love to see an option to Left/center/right justify the code.

Is this available? If not, please put it in the works. 🙂 Thanks for a great plug-in for us non programmers.
