Hi,

This kind of emails should go to the mailing lists (either -user or -devel). 
CC:d to lilypond-user.

dynamics work the same way as text. Have you read the manual section "Changing 
defaults"?

Yes, moving the dynamics is probably how it should be fixed.

No, but the problem of text collision in general is on the far-future todo.

BTW, there's no explicit bug in our bug archive about dynamics colliding with 
notes; can you send a short .ly example when this occurs?
