Since posting this, the pop up in the bar has become a really small square where I can't read or interact with any of the buttons, so I can't adjust any settings or turn off the highlighting if it's causing trouble without disabling the extension. If it is my end, is there a way to open up the pop-up in a new tab while I work out what the problem is? Thanks Works really well! Just one complaint that isn't your fault, the extension seems to use Imgur as the hosting site for the images on the menus, and Imgur has stopped operating in the UK. That means instead of the icons on the menu when I click on the kanji at the bottom right of the page, I get a placeholder image. It works when I use a VPN obviously, but I wouldn't mind an option to have the icons called from somewhere else if that's possible. Thanks
Has no way to turn off highlighting kanji on hover (the very subtle fade), which is very distracting when scrolling text. Would also be nice if it had some more settings for styling, such as underline thickness.
This extension is great. So many useful features that complements WaniKani experience. Thank you.
Hi, is there a way to manually set the wanikani level? I only did the free levels on wanikani because their systems weren't my cup of tea, so my api key is set to level 3, but I have since done much more study on kanji. I love the interface and everything, would love to give it a 5 star review but I don't think I can manually set the level which makes it almost pointless, so only 3 stars.
I am at the beginning of my journey learning Japanese, and I was excited when I discovered the WaniKani website. I was even more excited when I found this plugin – Kanji Highlighter! It provides such a perfect overview of my progress, with progress bars that motivate me to keep going so I can move those bars :D Thank you, developers, for the great job you’ve done. I am truly grateful that you are sharing your work with us :bow:
I absolutely adore this plugin for WaniKani. I can check my current progress in WaniKani at any time and it also covers JLPT kanji and Jōyō kanji progress. The leveling system keeps me constantly motivated :)
amazing website, helpful information, great UI
Awesome and super user-friendly experience! very useful :)
Thanks a lot for your hard work! I'm still only at WK5, but I'll use this extension more and more as I find websites with easy-to-read stories and as I progress through the levels ^^
Awesome extension. Allows you to have instant access to Wanikani info by hovering kanji with the mouse pointer, and to have a glimpse of how far you are from being able to read a text.
