The kerning issue is due to an existing bug with PhantomJS on Linux [1]. Hyphenation is a feature I've been wanting to do for a while but haven't managed yet due to the lack of a decent hyphenation engine for JS [2].
To quote from the readme, the program is "a very early version with a number of problems". But my point of "it's finicky but possible" still stands.
