Rated 5 out of 5 stars

Most of the dark Thunderbird themes look similar and, in my opinion, kind of ugly with the lines in between email messages. Dark Shadows XT removed the lines and favored a hover state to emphasize which email you're over. They also brightened up the interface enough to make it a dark theme, just not as dark-dark as the two ~dozen other themes I tried.

The one thing I don't like about it is the rounded corners. I prefer slight rounding at the edges if it needs to be done, but I'm less concerned with that than the colors so I'm still quite pleased.

Cheers

Beautiful, just some minor UI issues on macOS.
I sent you a mail detailing them.

Without a doubt, these are the best skin series for Thunderbird and Betterbird. They maintain their integrity even when the mail client is maximized on a 16:9 (widescreen) monitor, where most skins break on the left of the top bar. Additionally, the color contrast is just right, Amazing. True that a grey logo will play better in the title bar

Edit: Unacceptable is not the word I would have used (unless I actually used it); not for me would be closer to the truth. Now that it is gone, you get the 5* it now deserves.

It would be perfect except for the weird logo in the title bar. That logo wrecks the add on for me. It draws your eyes, it is ugly, and just plain weird.

Maybe you're right, the logo was too "unacceptable". I decided to remove it in the latest version (5.0), believing that my themes would be more liked without it :)

In my opinion a very good theme!
