Rated 5 out of 5 stars

Great addon! Darko is the only way I can have a (consistent) fully dark-themed Thunderbird (i.e., now also including the messages themselves).

One feature request: Is it possible to enable/disable Darko's dark mode automatically with the Thunderbird's theme preference? (I switch the OS theme twice on a daily basis manually - Thunderbird detects that and switches to the dark theme. It would be optimal if Darko could follow suit.)

Thanks for your work. Highly appreciated!

Edit: thanks for your reply. I already had found this setting, but I prefer switching themes manually - globally for the whole OS & apps. Alright, I will trigger Darko's dark mode manually in addition. Perhaps you'll find a way for automatic switching later (I guess Thunderbird's API is too restricted).

This review is for a previous version of the add-on (3.4). 

Hello,
There was some issue detecting dark theme from my addon.
But there is a "Automatic dark mode" setting where you can set time when it should enable/disable dark mode.

The settings page is a bit hidden in Thunderbird - right click addon icon / Manage extension / click the "Wrench" icon to access the Options page.
