It would awesome if FileMaker could dynamically autocomplete variables. So when you set a variable, FM could analyze all of the set variable script steps. Then any time you go to use the variable starting with $, it could underline in red (similar to misspelled words) if it has not been declared. I know this would be more difficult for global variables, but it would be nice to at least do this for local variables.
This should also be directly tied into intellisense.
If I type a $ it should bring up all of the local variables.
If I type a $$ it should bring up all of the global variables.
