Don't understand why people are complaining about this. It doesn't work for all websites but I wouldn't expect it to. Easy toggle on/off switch in the address bar area, no issues.

Adding exceptions does not work - (e.g. vk.com)
The exception is under "exclude from darkmode" but it is still applied to VK!
Useless for me!

What a great tool. Eyes are at ease at last.

The websites were all blank
