I use the “quickly move to folder” feature. I use a keyboard shortcut for “Move to folder”, type three letters, and hit enter. Sometimes though, I have to type the same three letters many times, for many messages > comes frustration.
Having the last used “Move to folder” on top of the folder list, already selected, ready to be used by hitting enter.
Another keyboard shortcut, doing the proposed thing directly.
I’m a user of Emails verwalten, archivieren / Nostalgy++ TB78 :: Add-ons für Thunderbird Nostalgy (++) on thunderbird, it does this, besides many more things.
