I LOVE IT! - Bricks for Thunderbird ROCKS! Rated 5 out of 5 stars
I've been searching for a theme with cool icons rather than the UGLY default stick icons that native TB uses.
I had been using other backgrounds by alfredkayser because of the icons, but wasn't wild about the color scheme (to many grays and blues already on other programs, Walnut2 was OK, just kinda dark).
"Bricks" lets me use a customizable background image so that the theme reflects a color scheme that light, and more to my liking. I also appreciate that I can opt to change the font too!
Thank you Alfred, my donation is on the way.
