- (2025-08-28) John Metcalfe: I was a long-time user of a previous version. It was such a shame when it started to degrade. Exporting from that one, I was able to import my records straight into this version. It's so good to see "it" back. It's such a simple extension, but does such a great job! 🌟
- (2025-08-20) Mureseanu Bogdan: I absolutely love this app. It's exactly what I was looking for. Now I can easily track my watched videos. Great job!
