Perfect for my needs. Tried yomichan and in comparison this is a lot easier to get going and easier on the eyes imo, no need to install dictionaries and therefore feels a lot less bloaty - this just works right out of the box. Fantastic work. Thank you.

In its current state this extension is incredible. Easily chipping away at a complicated syllabary that takes a significant personal effort to even begin to recognize the most important characters, right there at the tip of your mouse cursor. A wealth of information is presented an easy to read format that helps you reinforce all of the intricacies of the language, as you begin to learn them and recognize the patterns. Toggling on the additional Romaji text really helps to speed up the rate at which you can memorize individual symbols, by having a reminder always ready at a flash. 理解チャンプ、「最高」！

This extension is literally flawless. It does translation, and it does it the best way possible. A lot of information is shown but the results are presented in a structured manner that is easy to understand. It is responsive and the UI is intuitive and highly customizable. Oh, and now mouse support is added. I literally cannot think of any way this extension could be better. Thanks!
