Very nice theme! Only one issue: for some reason, the folder colors, in the properties, is black instead of the blue the folder actually is. The issue is that "repairing" a folder makes it actually becoming black. To restore it one needs to change theme and re-apply Dark Night Arcturus X

This review is for a previous version of the add-on (4.1). 

Thank you for your opinion and information about the problem. It turns out to be a Thunderbird bug (not the theme), which occurs if the theme defines custom colors of folders and it has already been reported to Bugzilla.

Excellent, the only thing i wish the dev would add are :

- possibility to have the very nice button font white or other colors cause black is not very readable when not selected.

By the way thank you dev for your great work

Update: Dev fixed the calendar event color issue (thanks man!), and so back to 5 stars because it really is the best theme I have ever seen.

Five stars all the way ... except for the latest update. While gorgeous, the latest update (and as others have said) screwed up the colors of the Calendar categories and now they are hard to tell apart. Please fix this. It is a real hit to the Calendar "at a glance" functionality. Thank you.

Hello. fixed. Please, download new version of Dark Night Arcturus X (4.1) from my private Add-on home page (https://www.yonak.pl/tbthemes/) or wait a few days for approval it by Mozilla and then update the theme directly in Thunderbird, @nyquisteroux

Thanks for the Calendar colour fix. So 5 stars now.
This is a very nice, uncluttered dark theme.

I have been using Monterail theme for some years. Now it is no longer compatible with a newer version of Thunderbird. I tested several alternatives and found this theme quite similar to Montrail.

Excellent theme. The contrast in colors makes it far easier to use Thunderbird all around. The darker blues and bold greys contrasted with the blue highlighting is just an elegant experience. Very easy on the eyes, and increases usability. Thank you very much.
