Maybe someday, but not at this point.

I'd love to support other languages too, but at this point it isn't very feasible. I'm just a single man, and this is just a side project, so I simply don't have the resources to even do everything that I want to do with Japanese (and there's still so much more I want to add/improve!), never mind branching out into other languages.

I’m asking because I’m learning Mandarin at the moment and the features you listed are just so freaking cool. Wish to have that!
