The extension works wonderfully for anyone that wants a monochrome experience of the web.

For me however, I like browsing in colour.
My use case for greyscale is to stop getting sucked into the scroll hole.

This only happens on a handful of sites.
ie. Linkedin, facebook, reddit.

AFAI can tell the extension's 'blacklist' allows certain sites to operate in colour.
I'd love if the extension would let users choose what to greyscale

Current Modus Operandi:

Browse the web in grayscale. (w/exceptions)

⤷ Active = 🌚 Greyscale everything
⤷ Inactive = 🌞 Colour everything.

Exception list
⤷ Blacklist → 🎨 URLs always in colour

Suggested MO:

Browse the web in grayscale (or just distracting ones)

⤷ Active = On
⤷ Inactive = Off

⊕ New toggle
Greyscale [ Everything ⁄ Site list ]
⤷ Everything = 🌚 Browse the web in Greyscale (with exemptions in Colour)
⤷ Sitelist = 🌞 Browse the web in colour (with exemptions in Greyscale)

Exception list
'domain' + behaviour flag ( 🌚 grayscale ⁄ 🌞 colour )
⤷ Everything mode uses 🌞 flags (colour exemptions)
⤷ Site list mode uses 🌚 flags (grayscale targets)

I'm aware this is the use case OF ONE.
Hope it's useful! Thanks again.
