please add comments into a fiddler AutoResponder. And maybe hierarchy view for i can create folders and create responses inside folders (for grouping). With group switch on|off.
To add a comment to an AutoResponder rule, select it and hit 'M' or right-click it and choose "Set Comment."
Enabling Grouping of rules is an interesting idea; it introduces complexity (and because of how ordering/precedence works, it might be impossible to do this in a way that really works), but the idea of enabling/disabling sets is a fine one.
