Hi Dan Kernan - these are all excellent features and suggestions. Unfortunately most would need to be added to the roadmap, not available today
1) not currently, but great idea.
2) not currently, but great idea - I could also see summarizing this information by page tag in some of the cards.
3) you can sort already. filtering is in an upcoming alternate view we are working on
4) can you go into some more details here: how would you want to define the rules about what to filter out? would it vary by individual? reasons why you would want to also helpful
5) not currently - may I ask why?
6) not currently - good idea
7) you can customize the default alert that gets sent to sales reps and include a link to profiler, for example in the header.
