Write an Addin that does something useful that MZTools doesn't already do. Some things might be the ability to examine all your variables and make sure that their names conform to a set of rules that you can define, or a "lines of code" counter (what a "line" is would need to be defined), or a dead Sub/Function finder, or all of the above.
That would leave out us Java developers...
