The output in their screenshots look nice, but it looks like there are some cases that aren&#x27;t handled as cleanly as I suspect LilyPond would render them.  In the &quot;Praeludium 10&quot; screenshot on their website, look at the first sixteenth note in bar 21, for example.  It&#x27;s rendered really close to the left margin (and obscures the tempo marking); most printed scores would include a tad more padding for readability.  Would be interesting to read their layout algorithm and compare it to Lily&#x27;s (I guess I can!).
