When I first got my III, I didn't use the editor at all, specifically because I didn't want to come to rely on it, to HAVE to have a computer to change stuff. That's worked out fine for me. I can get around fine on the front panel. There are some operations, bulk changes in particular, that are definitely faster in the editor, but the basic functionality of navigating to specific parameters of specific blocks and changing them most definitely isn't a problem.
