1. Peek at annotation when hovering on highlight
2. In scope dropdown, colorize groups with annotations and display counts
3. Highlights are dimmed, bracketed by «angle quotes», and followed by a link icon, ????, which opens the associated annotation inline for viewing/replying. (Highly experimental, especially on PDFs!)
4. Remembered tags are drawn from a Google Doc which is specified in the extension's Options pane. It defaults to https://docs.google.com/document/d/1XZZEtmMSgSWDL6y5086SoYs0bkLvoO0qumLf-qVxrZU, but you can change that to another doc that has a list of tags, one per line. The doc needs to be readable by the extension but you can keep the URL secret, or share it to use a common tag list with collaborators. You can still create ad-hoc tags too, but this extension won't remember them. To remember a tag, put it in the doc.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
