[mu4e rfe] Duplicate Message Indication

[yamanq]

Is your feature request related to a problem? Please describe. Thank you for maintaining mu4e. I manage a gmail account using mu4e, which results in duplicates if a message is labeled. I use automatic labeling to mark certain messages as they arrive into my inbox. However, using mu4e with duplicates hidden, I only see one copy of the message, with no indication that it is a duplicate (and therefore labeled). I do not want to show all duplicates because every message in the Gmail system is duplicated to [Gmail]/All Mail.

Describe the solution you'd like In the Maildir header line on mu4e:view, list all the Maildirs including duplicates.

Describe alternatives you've considered

• Include another line in the mu4e:view header such as "Duplicates: "
• Show an icon in the Flags column that indicates a duplicate. This is not ideal since it doesn't show the user where the duplicate is located.

I suspect the "icon in the flags column" one is the only feasible (i.e., not requiring too many changes).

Thinking about this again, I'm not sure if that solution would be helpful for the Gmail use case, as all mail would show that it is duplicated in this case.

That's true; there's no real need to mirror the complete Gmail folder tree, but anyway, I guess I'll have to decline that RFE then, as it's too much work.

Frankly, the problem is with the mismatch between gmail and the the local file-system. Trying to work around that with mu4e is hard... too much work, so have to decline this... sorry!
