I have to say something that keeps me awake at night: Current LilyPond flags look bad! They look so bad that I have to use straight flags instead. The big problem for me is that flags on a single note have different shapes. The lower flag is wider than
flag above. I talked to Janek Warchoł and he said that this output is intentional and explained to me everything. However, those christmas-tree-flags (as I call them now) still make me sick, because they look inaccurate. Does anyone have the same feeling? And please take look at the atachment - this is how perfect flags should look like to me.
