A tool that allows you to manage and view YouTube comments with timestamps efficiently.

Features: 1. View the concentration of comments using opacity of displayed markers. 2. View comments containing a particular timestamp. 3. While playing the video, view comments with timestamps like a live chat replay. 4. Customize the primary colour, block size of the markers. To use Tempus, just make sure the extension has been installed and enabled in your browser. Then, you can head to any YouTube video, where the extension will collect timestamps from the comments and display them under the video progress bar. The settings, which are accessible through the Tempus icon on the top-right of your browser, allow you to: 1. Configure the block size of the marker (value can range between 1 and 20 seconds, default: 1) 2. Toggle HeatMap markers (default: enabled) 3. Toggle the comment live replay (default: disabled) 4. Toggle the marker on-click commment view (default: enabled) 5. Configure the primary colour for markers (default: #ffb347) Check out the source code here: https://github.com/knightron0/tempus Enjoy!

It stopped working on the last few days EDIT: It got fixed. There are still good developers left. I only wish now that we could click on a timestamp without the video changing to that part. But everything else works perfectly.

very useful for watching videos, whether for educational or comedic purposes, only flaw is that it is a bit slow on startup, but I suspect that that is out of the developer's hands. love it!
