When user works with AutoResponder a lot, it may contain lots of rules, most of them are probably start with https:// or regex:. To understand what rule does, especially after some time or when import/export for colleagues the context is fading. I propose to add new column with label/comment which will contain any string for rule name or any explanation what rule does. It may be editable cell so user will be able to change it "on the fly" without needing to select rule and then select input on the bottom of the panel.
Also would be great to have folders or categories, then user will be able to sort rules for different hosts or purposes.
