The Variable Window

The most useful feature of the variable window was being able to find out precisely where a given variable was declared, instantly. I experienced several situations when I was modifying g++ when this would have been useful. When I was scrolling through one function that was several hundred lines long, I noticed a variable whose value would be useful to the navigator, but it took me some time to find out if it was a global variable or not, to see whether or not it could be used by my functions. If a variable window had been available, I could simply have selected the variable in the code and asked to be shown which scope it was declared in.
