ReadingRuler is a free Chrome add-on developed by ruinunes. It aims to assist users in reading texts on the internet, specifically pages with wide paragraphs. By hitting the combination of Ctrl + R on both Windows and Mac, users can activate a semi-transparent line that appears on their screen. This line serves as a ruler to help them focus on one line of text at a time, making it easier to read and comprehend.

The latest version, V3.1, brings numerous improvements to the extension. The ruler now consistently appears on the screen and is no longer invisible. The new popup layout offers two additional options: users can choose the color of their ruler and adjust its visibility. The core code has been updated to enhance performance, including the removal of unnecessary calls to the background script and the improvement of overall functionality.

Previous versions, such as V3.0.1 and V3.0, resolved issues, rewrote the code for proper functionality, and updated the manifest to V3. The Alt modifier key support was dropped, leaving users with the option to combine Ctrl, Shift, and a keyboard key to activate the ruler. The extension icon now includes a badge to indicate when the tool is active.

Overall, ReadingRuler is a valuable tool for those who struggle with reading wide paragraphs online. With its easy activation and customizable options, it offers a seamless reading experience. Try ReadingRuler today and make reading on the web more accessible and enjoyable.
