Another a couple of things I would like to add is this:
1) In the segment field, when opening up an existing filter, it would be nice to have the history of what was exactly done prior to the merging, intersection, or trim options. Usually what I find is that if there are more than one users working in the same Eloqua account, there's a lot of editing and down the road, we tend to lose track of what we did/what happened. So it would great to have a history option (maybe place it under setting area or create a new 'history' field in the right-click option) where we can see exactly what happened if there were more than 2 filters that have been mixed (merged/intersected/etc).
2) In the Campaign Canvas, it would be awesome to have more details under the Campaign Audit Report (ie. What was edited in the campaign exactly).
Cheers!
