Hi, Situation:
I usually have to switch between =mbox and =outbox to check the mails on a specific topic we've gone on for a while. Sometimes, another one, say =work/project-A, needs to get involved, too. The same case happens among =mbox.mutt, =outbox, and =mlist/mutt for my daily life. (=mbox,mutt is the in-coming one, =mlist/mutt is for saving the mail I'd like to keep.) Request: Is it possible to have a "cross-mbox-threading" function as following: 1. A variable, say ref-mboxes (Type: string, default: "=mbox:=outbox"), to specify related mboxes to reference. The mailbox in front of ':' is the main (or working) mail box, the right side lists the mailboxes to reference. You can add more reference groups by separating them with ';'. 2. A variable, say cross-reference (Type: boolean, default: no), to turn on or off the cross-reference. It will make the referenced mail appear/disappear on the index. 3. When you work on your coming-in =mbox, you can see the threading also reference to those mails in =outbox. (with some display difference) Not all the mails in =outbox appear in current work session - only those belonging to the threads in =mbox will appear. The mails of ref. mailboxes can be read but are read-only. User can not delete or edit them. (unless another variable 'allow-change-ref-mbox' is turned on) It's to avoid confusing. I found such 3-way cross-reference is quite common in my life, and hope it to come true. Thanks. best regards, charlie
