Two spacing bugs: tuplets, staves...plus: ottava/8va parentheses on continuation?

Sorry if I missed something.

I'm attaching a score excerpt which demonstrates two spacing bugs.

1. The tuplets are spaced unevenly. (See e.g. the quintuplets in bars 4-9, and
the triplets in bar 8.) 

2. The staves are spaced unevenly. If this is by design, I think it should be
redesigned. If anything, the distance between Piano I and Piano II should be
greater than the distance between the right- and left-hand staves within each
piano part. As it appears, the opposite is true. I'm not sure why, unless this
is a bug.

While I'm at it, I'll mention...

3. that the ottava (8va) bracket, when it continues on the second line, should
really be parenthesized. I didn't see this mentioned in the list archives when
searching for 8va, ottava, parenthesis, parentheses, parenthesize,
parenthesized, and combinations thereof.

Maybe I should have broken this up into several messages, but I'm not very
familiar with the bug reporting procedures and not certain whether these bugs or
possible features are known, or if I've missed something. If I should have
posted this differently, please advise me.

Anyway, the score in Lilypond markup follows below.

Regards,
Marcus
