Does the job well for what I kept Rikai around for, just wish it had a sticky mode so I could select text from the popup. Audio from utilizing languagepod's assets like Rikaisama/Yomichan would be nice too, but I don't care as much about that.

Definitely a great, promising start for a webextensions replacement of Rikai though. Looking forward to seeing how/if this is expanded upon, as it seems even more responsive than the old Rikai was so far.
