Would it take long to implement something like this?

Would it be easy to develop an IDE script which does this kind of thing? If somebody was to develop it for Xojo, would it be convenient to have one that works at runtime.

If you forget to set the tab order and you have lots of controls it could help out a ton.

Has anybody done anything like this before?
