ReadingLine

Updated review October 2023: Waste to install it. It is not helpful at all. See my original review... Original review: Not impressed. All it does it add a highlighter line. There are zero controls over it. Uninstalling.

I DONT UNDERSTAND HOW TO USE IT SORRY

Most of the best browser extensions offer flexibility with their settings and configurability. This is a competent piece of software, but not nearly as good as the previously stated. This extension should also accomodate PDF files and other forms of content that the developers left out. The option to add shortcut keys is also present in many other extensions, and it isn't here. Adjusting the settings for the color, opacity, and other attributes of the line should have been included as well. There are simply too many to enumerate. In conclusion, this is an amateur-level program that was not given enough attention.

Meh. not great.

It doesn't seem to work on ao3 which is the site that I need it for, but it works in other places just fine.

Only one that works on PDFs, but line can be too thin and color too light. Customization is needed to make it perfect.

I love it! Very useful when you struggle with reading long texts. I wish there was an option to change the color and opacity of the ruler, though. That would be perfect!
