vertical spacing of articulations and tuplet indications

[Matthew Easton]

I just started playing with Lilypond a few days ago and it's a gas. I find it 
much more intuitive than Finale, which I've also recently spent some time 
with.

A problem spacing articulations and triplet indications.  Not sure if this is 
a bug report, a feature request, or a plea for assistance developing a tweak.  
The case is a drum part with 2 "voices" on a single staff.  The "+" and "o" 
of closed and open hi-hat, as well as manually added articulations are too 
close vertically to the triplet number and brace.  

Is there a way to manually adjust the height of the triplet or the 
articulations?  Which should go on the outside?  I couldn't find an 
unambiguous illustration of this in a published score at hand.

You can see an illustration at http://sublunar.com/example.png

Is it my imagination?  The 3rd triplet group in the first measure actually 
seems to pull the "3" in closer to the beam compared to the first triplet 
group.

In measure 2, I manually added articulations to the snare drum note.  I see 
that with manual indications, the triplets behave exactly the same as with 
the hi-hat.  

Thanks for a great piece of software.
