I would love this but for some reason "Custom" doesn't just turn off the google page colour, it ends up making your custom colour one page, and the next page will be the background colour, and so on.

This would be a perfect extension if you never have to change the page colour to differentiate projects etc. I prefer a beige background for our main project, and grey shade for another, and a really dull robbinshell for my third project.

Only works on Google Docs "documents". While one would assume a dark mode extension for Google Docs would work for ALL services under the Google Docs umbrella, or at the very least Google Docs spreadsheets, it only works strictly with its namesake, which to me would be like adding a dark mode for YouTube videos, but thrusting the user back into light mode as soon as they view a YouTube livestream vod. Its description isn't incorrect, but it is just a bit misleading when I can still be on "docs.google.com" and not have a dark theme.

Doesn't even affect the colors on the main screen (where it lists your documents for you to choose which one to view), making it really jarring to switch between light and dark repeatedly.

I'm also surprised it doesn't have the ability to invert black text (to make it white) without also inverting all other colors. Works fine for grayscale colors, but when it also HAS to turn red text cyan, it makes it hard to view documents formatted by/for people who don't use this extension. The only fix for this is to turn ALL text grayscale, which might be fine for people who don't mess around with formatting very much, but not for me.

All in all, technically does what it advertises decently enough, but is lacking in features. I suppose I'll keep it installed just to darken the bar at the top if I can't find a better solution.

Some images in the document become blank images

Does not work on Google Sheets, which is where I need it most.

It's not bad, but it ONLY changes the document editing page itself. The rest of Google Workspace is unaffected, including the page where you load up different Docs. Not what I was looking for.
