I've still havent't figure it out how to open an email in a new tab with just a single click when inside GMail. It. used to be possible, of course, like all HTML links (by clicking the middle button on my mouse, for example), but since 3 or 4 years (at least) that feature disappeared. I'm still upset about it and that is why I consider GMail "the worst" piece of software I use everyday (it's also because I don't use that much "different" pieces of software).
I use that often, my only complaint is that it you close the main window, for some mystical reason it decides to also close all the other tabs opened that way
Thanks for that, sincerely. Still looks a little bit awkward because it only opens the email message in sort of its own thing (no menus like in the "main" tab) but it works.
