I spend a great deal of time in VS debugger on a vary large Intel Visual Fortran project. I don't know how language dependent such a thing would be, but what I would like is the ability to setup a break "point" that is not tied to any specific line of code, but rather to a specific variable. And then the debugger would break when that variable changes value (with conditions). I often don't know where in the code anerroneous value is getting set and this would save a tremendous amount of time for me.
