This is such a well designed extension. Has worked exactly as needed and has a treasure trove of useful information compactly shown. The new mouse control features are so useful as well! Thanks for all the hard work.
lit
This is almost good, but it has this massive disadvantage: you can't mouse over a popup and scroll down it, apparently. I could do this out of the box with all the popup Japanese dictionaries I've used to date EXCEPT this one. There also doesn't seem to be any option to customize the popup time itself. So I'm pretty much out of options if I want to read all the meanings under a popup.
i love you
this extension id goos, the extnesion is good frankly, -max
a double-click function. please. ctrl+alt(or something)is uncomfortable.
Its a really good extension for Japanese learner. But the really annoying thing is once you move the pointer the popup gonna change. So u can't check the kanji details. And there is no options to change that.
I have been using the Rikai family (lol) for YEARS. It's simple, you install it, ENABLE, and bam. You can hover your mouse over runes and it gives you a Pokedex pop out (customizable btw). It also shows the PITCH ACCENT. OTL You literally need this.
Has more features than any other alternative. Smarter for various translation context, like converting year, date format, and currency.
Excellent extension for learning Japanese.
