Hi Patrick,

yes, of course. I didn't use tremolos very often while playing around with
the new tablature appearance which yielded to scm/tablature.scm, so
I overlooked this.

That's great, I'll provide a patch within the next days.

The #'beam-thickness of the tremolo beams is defined in 
scm/define-grobs.scm as .48 * staff space.
In ly/engraver-init.ly we have the staff space spread to 1.5 * staff 
space, so it would be optimal to
define the #'beam-thickness in TabStaff being 0.48/1.5=0.32 to ensure 
the tremolo beams are equal
in size for normal and tab staves.

What do you think?

Greetings

Marc
