I think this is a great idea, but I was also thinking about it the other day, and I thought about an auto-complete like Visual Basic that could help people make repeditive scripts.

It can display things like:
the variables in the variables section
identifiers and aliases in the current file and alias section (aliases can have their identifier counterpart in the list too)

But thats just an idea.
