Hey everyone! Thanks for the feedback on this. It's a fairly broad request which, as it sits today, is at least partially implemented (Class of, for example, is a filterable field on lists now!). And in general, you can rest assured that we will be adding more and more filter options to lists over time. For now, I am going to change this idea to be more specific (Filter lists based on Gender and Ethnicity). If there are needs/requests for other specific filters that you would like to make sure we're aware of (like communication preferences), I would ask that you go ahead and create a separate idea for it so we don't end up with just an ever-expanding, never completed idea to make list filtering better. :)

Also we need to be able to filter out solicit codes/communication preferences. I'm building lists in order to get base numbers for my participation reports and I want to be able to filter out those who we don't solicit. It would also be nice to have that as a filter in retention reports. I love being able to pull a quick list of LYBUNTS, but then I need to save the list as a static query in RE in order to be able to pull out the people who we can't solicit and/or send mail to. The filters that are available are very limiting.
