Just thinking out loud here after some casual Googling left me unsatisfied . . .
I like Thunderbird, mostly, but while it has an extensions interface, I am finding it lacking for basic customization. For example, I like to toss e-mails in an “archive” folder . . . but as far as I can tell I have to drag messages to the folder every time I want to archive them! I dug around and found the “file” button . . . but that thing is just awful! I’d like to . . . press “a” or something, or click an icon, and get the mail archived that way. (Like, to delete a message I press “delete” . . . eh?)
Has anyone found a useful configuration option / extension / doohickey to realize this stuff? Or should I re-acquaint myself with mutt for e-mail triage?
