Thanks for the feedback. You’re right that there is a small delay when switching to fullscreen. That delay is partly intentional because the extension needs a moment to process the video state and apply the filtering correctly. Removing it entirely without breaking the core functionality is difficult, but we’re still working on reducing it as much as possible.

The RAM usage is more concerning though, and we’ll look into that separately because it shouldn’t keep growing unnecessarily with every new tab.

Appreciate you testing it and pointing these out.

Thank you so much! It is amazing to hear how it connects with your own language learning journey. Glad it is helping you now :)
