It's a kind of spin-off of Bug 1010150
and previous emails

> * Debugger: Rename JS variable and propagate in the code 
>(issue analyzing the scope.)

> # Un-minified JS crazy renaming

> Once the JS has been un-minified, the possibility to change 
> the value of a variable and/or function.
> 
> Use case: When a JS is minified, sometimes the variables and 
> functions names are called things such as a, b, c, etc. which 
> makes it harder to read the code.
> 
> What the feature does: If for example a function is called "a", 
> I can select it anywhere, somewhere in the code, rename it 
> "a_better_name" and it will change the value everywhere in the 
> code where it has been used. (it should warn if the name is 
> already taken).

This is a feature request. It would be nice to have, but isn't on top of our priority list at the moment. Assigning P3 to this for the time being.
