I have quite a few email filters going on with separate folders, and am trying to get a threaded view like the following:
All emails (across all folders) in conversation with emails in my "Important" folder.
The reason is that I get a lot of email, and most of the time I don't care, except when I get referenced (for example). This happens quite a bit with Jira emails; once I get referenced, I want to see (and then delete) all the messages that I've missed because they weren't important at the time. If I don't delete as I assimilate this knowledge, it makes my "low priority" scan a lot harder since there's fragments of "important" tickets in there...
