This is a **solid** add-on to up your efficiency in LingQing within LingQ! I love it and will continue to use it — though maybe in its other forms since I love more than one Rooster Extension. I'm checking it out within the Master LingQ (Premium) addon (*see Rooster's web extension support page for info on that*) soon.

With Rooster Observer, learners can see the LingQ(/potential LingQ) add grammar tags, add meanings (*more than one in the most recent update*), toggle line starters for your notes section of a LingQ, and update LingQs that you've already made/ignored.

My target language is Korean, and I've found a smoother process in LingQing via Rooster Observer since it's compact and comprehensive.

My setup is Rooster Observer (*while I'm in sentence mode*) + Rooster Hotkeys to LingQ and study more efficiently for me.
