Quarter-tones

So, Flat just added "quarter-tones" (which is basically a pitch in between a note and its corresponding sharp or flat). They're really interesting, but they sound strange if you're not used to them. I will try to write something in a half-flat key sometime, but I don't know when it'll happen. I don't want to have to put in every quarter-tone in manually. Maybe if we had half-flat key signatures...
