I just tested Proton Doc again after a year and got flash banged as everything on my PC is in dark mode and a pure bright white side is opening. I know that even Google Docs don't has a dark mode (there are extensions though), but at least you can change the paper color.
Sure a dark mode in a writing app is a bit tricky, because you need to separate the UI from the paper/write section , as it is not for everyone to write white on black (I prefer black on a slightly grey).But you can make the Font and Paper background color configurable and use the dark mode for the surrounding UI as it is in the Proton Email client.
I can't use flash bang 100% bright apps anymore, as my eyes will hurt after a while, it just seems from a different era.

The introduction of sheets is awesome but I really think this should be prioritized. It's such a small effort that would make a massive difference to the platform. Would be nice if the way mail themes work could be extended to cover docs too.

Very important, especially for health reasons!

darkmode on documents please. Also need a spreadsheet, even if basic.

Please
Your drive is very handy and the font is great and really comfortable to read, but the light is giving me headaches. I need a dark mode asap!

GG, this idea is only a year old. I guess it will need at least 3 more years before they even consider adding a black mode for Proton Docs, since the Email's Dark Mode suggestion has already been here for 4 years, LUL

This would set this apart so much and I would immediately use it over Bear.

I completely agree. All the other apps have a dark mode, but this one doesn’t. Having a dark mode is essential, it really needs to be added.

I love the text editing options but can't use it for extended due to photosensitivity. Please add a dark mode!

This is the primary reason I do not use it.

100%!! The lack of dark mode makes it difficult to use at night. Help us out!

please prioritise this in the next update. Really need this.

Agree as well. Not sure why it has been left out? Drive, calendar, mail etc all have dark mode, why not docs?

Totally agree with this. Dark mode makes such a difference for long reading or editing sessions specially at night. It would be great to see Proton Docs include a dark theme option like other Proton apps already have. Looking forward to it

As a writer, PLEASE, let me use this in dark mode natively. I can already use Proton Drive with different themes, let it extend to the docs, I am begging you.

Please please. Feel free to ask Google for tips :)
Or from Proton members who are great with CSS?

Request to implement a setting in the Docs to enable dark mode/theme. This feature is a critical point for me and many other users, and it's the main issue keeping me away from using Proton Docs as my daily driver.

I agree with others - the Proton apps have it, docs should too - it just makes the experience a LOT more enjoyable!

if theming is implemented i would love to be able to also provide my custom theme. this does not need a complex implementation, just proving a file that defines fonts and colors would be sufficient

This would seriously make the transition from Google Docs easier!
