I would like an info icon next to saved lists in the filter, where users can hover over it (or click) to see the definition of what the saved list does.

Right now, we have a "data dictionary" in a spreadsheet, but users won't want to go outside the platform to find that info. I think the list page should allow us to add descriptions to a list, and those descriptions should be easily viewable on the people page filter. This would make the filters easier to use and understand for newer admins.
