It doesn't seem like this extension is being actively maintained as it hasn't been updated in 3 years and has some glitches. It worked for two months. Then it started making the text invisible on entire pages in Docs. The page would go 100% dark even though there was text. Selecting the text on the page helps but this problem continues to happen. Also, I didn't like the way that this extension made the column and row lines appear in Sheets. If this is meant to be just for Docs, then it shouldn't be applied to Sheets. It would be nice if this extension made the default grid lines' color a lighter grey color so it would be more visible, or have an option to config colors.

Installed this per reviews on Docs After Dark. This one's so dark I can't see the typing cursor lol. If y'all could fix that, it would be perfect.

uses a filter on the whole page (you might need a good gpu for this)

Looks like a simple inverter. Not what I was looking for.

In desktop it works really good, but in sheets the right panel that shows conditional formatting is all black.
