Of the hundreds of folders I have, I usually only file into four or five different folders. An option to highlight the last N (N configurable by the user) folders that messages have been moved into would help. Thanks. Reproducible: Always

The folder pane basically already has this via its (nearly undiscoverable) "modes". If you click on the left and right arrows at the top-right of the folder pane, you can reach a "Recent" mode that only shows recently accessed folders. Alternatively, there is a "Favorite" mode if you right-click on the folders and mark them favorites. You can also directly access the modes via "View... Folders..." If you really want highlighting of recent folders rather than separate modes, I think that is best dealt with in an extension.

Thank you Andrew, I use the Recent Folders heavily. However, this request is not requesting that _only_ the last N folders be shown, rather that _all_ folders be shown but the last N be highlighted.

Dotan, I hear you. see Bug 456444 - decorate folder in folder pane that is the current target/most recent for move again/copy again

I would agree that bug 456444 is a specific case of this bug, for N=1. I am tempted to mark this a dupe, however, I think that it would be better to mark that as a dupe to this bug as this bug is the more general case. What do you think?

I had given this some thought and concluded they stand on their own, because this bug might be fixed in a way that doesn't accomplish bug 456444, and vice versa. but they are closely related ... so setting dependency (weak depend.) and not an abuse of dependency field IMO :)

I've modified bug 456444 to current target/most recent move again/copy again folder name should be displayed in UI or decorate target folder in folder pane
