Description:
I don't know much about the basics of coding so it will probably sound like I think it's easy:
Is it possible for you to add optional support the newest mecab Unidic tokeniser?

I know it's very heavy(1GB+?) and it doesn't automatically translate to better parsing but it's probably better than Ipadic, so ideally, since anki has limits, you would host the files where you host your dictionaries files or gives the instructions and links so we can do it ourselves.
