Nice. Instant download.

EDIT: the flash is a bit extreme on dark mode, and hides the text. Would be good to make this just a light alpha overlay which fades the same way, or / and ability to just turn the flash off

Hah, didn't even know Twitter had a dark mode.

I've updated the extension to use a dark-mode-friendly highlight color when appropriate. The update should pass the web store review process in a couple days (hopefully).
