Hi Antheo,
Yes a short sample would be nice but as it is a layout question it does not
makes sense to shorten the code. Here is the code i wrote:

OK -- now I can see what's going on. =)
1. If I'm not mistaken, you're trying to adjust not the overall spacing, but specific
spacing choices/proportions based on note length. It's easy to match the length of the
entire snippet to the desired output/example -- by tweaking common-shortest-duration --
but you want (e.g.) more space left for a dotted eighth than Lilypond's default. I
believe this isn't controlled by "common-shortest-duration" only, but by other
settings — I don't know the exact details, but I imagine there's a relatively easy way to
set these proportions as you would like them. Maybe someone else can answer more
completely.
