Very nice style ，i like it very much :)~ but In the 2K or 4K Display resolution，at maximize the window to full screen,in the upper left corner Label bar，there is a little bug of skin style about High brightness colour block not aligned。Hope to Fix it，Thanks~

very clean theme. i've found no other that's as pleasing to my eye. used it from the beginning.

No longer works properly with 78.10.0. When folder is selected (Inbox, Trash, Received) the folder name "disappears". Needs updating!

Awesome

Thunderbird never drop the letter. ^^

A pleasant and discreet theme.
The downside is it is too narrow when maximized. I find on a 2560x1600 screen, the back ground graphic is short on the left side of the screen, leading to a black square under the Icon, File/Edit menus.

Sehr leicht zu bedienen

Semplice e bella

A handsome, minimalist Thunderbird theme. Very easy on the eyes. Will be using this for a long time to come.

love you blue bird

simple and beauty. And not black. This is what i looking for.

I really love the simplicity of this theme. It addresses the many frustrations I have with the current fad of "flat" interface design (e.g. form elements or tabs becoming indistinguishable from the background). Well done!

As already said - it's simple and clean theme without any stupid fancy decorations which only makes your eyes hurt :) just love it !

Simple and clean!

sobre et classe :)
de plus va bien avec le thème "air" de kde je trouve.

I love this theme, but the one thing that irritates me is that when you mouse over a tab next to the currently selected one, rather than the current tab appearing to be in front as with the default theme, the tabs merely overlap. But I use this theme for Thunderbird, and Firefox Suave for my Firefox, and over all I really like the look.
