Looking For Google Extension Developer

The goal is to add certain new UI features and functionality to Youtube on the front end. There are multiple approaches that we can accept: A browser extension that works in Chrome at the very least, and in all major browsers if possible A simple HTML5 site embedding functionality provided by https://developers.google.com/youtube What are the UI features that we need? We use the new UI features provided by the Chrome Extension Pockettube (https://yousub.info/) as a starting point. Please take a look and try out what this extension does. From there, we need to add the following: Allow the user to add their own personal tags to individual videos on YouTube Allow the user to add their own personal tags to individual *frames* of videos on YouTube Allow user to customise what is shown in the Up Next queue If interested, pls apply on Upw.
