We can create lists. But those lists are not easily managed. Names, locations and other info are not sortable. And we can download our info which also has our friends list, but it’s a text document that is not sortable and names are only alphabetical by first name. Also no links to the profiles. So I created a spreadsheet where I can sort various info and click to any profile. It’s a good way to discover who unfriended me. I can either quickly click through profiles, or periodically download my info from Facebook and easily compare lists. Let me know if you’d like a template.
