Among the many things the late, lamented Eudora email client spoiled me for was, when I checked my mail, opening all the mailboxes that had received mail in new windows. That way I could click through, looking at each mail window and closing it when I was done, and be sure I had seen all my new mail.This is a javascript you can paste into the FiltaQuilla addon’s “Javascript Action” filter action which brings this behavior to Thunderbird.Following are the explanatory README, the script code, and license, embedded from my repo on Github at https://github.com/kupietools/filtaquilla-open-mail-folder-on-receiving-mail. Mike Kupietz , a reluctant scion of the postmodern age, is larger on the inside than the outside: perhaps not a composer, but a producer and arranger of sounds; nor a writer, but an avid writer-down; an occasional author of doggerel; an erstwhile urban hermit; and privately a man of very great ardor. He is, if now resigned to never succeeding at those personal and artistic pursuits he holds most dear, unwavering in his determination to fail at them as entertainingly as possible. He is currently in what he calls the "red bathrobe period" of his life. If you're wondering what all this has to do with FileMaker development or IT consulting: you done taken the wrong turn, this river don't go to Aintry—Mike's professional services are on his San Francisco FileMaker Pro consulting website.
