Second set of impressions: 1. Import & Expect should be together. I also think you need three "Add" buttons: Add New Rule, Add New Rule Set, Add New Rule Group. 2. (Minor) When I adding a New Rule, I think it would be nice to add an optional Description or Notes section, where admins can free-form type in notes (maybe to help them outline the rule's ECA, or remind them how the rule fits within their rule group, or whatever. I can see how a notes section might help me personally plan out more elaborate rules). I'm also not sure why there's a title for every event, condition, and action since all I personally do is re-type the exact action, condition, and action. 3. (Minor) Rule Triggered When - I encourage you to consistently utilize present tense: "is updated / is deleted / is changed / is moved." 4. (Minor) ECA Categories - You use the square checkbox icon for the major category headings for Content, Content:Pages, Content: Forums, Content:Gallery ... except, those are more of category headings and not choices. 5. ECA Categories always includes pre-selected first option - In every event, condition, and action, the first option under the Content category is always selected and I can never uncheck it.
