About

Lightweight and customizable alternative to a feature normally reserved to Reddit gold users. It requires minimal permissions and syncs between browser sessions! It supports RES (Reddit Enhancement Suite) night mode and custom CSS!

Note that highlights won't show until the second time you visit a comment thread after you install the extension.

Please report any problems you encounter to github issues page.
