I've been using the collapse_flagged patch for a while (including the newest versions of mutt) and think it's really useful- other people might as well. It adds a configuration option, collapse_flagged, which works pretty much exactly liked the existing collapse_unread configuration option. It makes it easier to sort/parse/eyeball large mailboxes, or mailing lists. The patch is available here: http://software.lpr.ch/Mutt/patch-1.5.4.lpr.collapse_flagged Reproducible: Always Steps to Reproduce:
