It would be nice if the whole note tremolo (in the first bar) could be angled like the tremolo in the second bar.

\version "2.11.20"
\paper { ragged-right = ##t }
\relative c' {
  \repeat tremolo 32 { g64 a'' }
  \repeat tremolo 16 { g,,64 a'' }
}

This might be related:

The "stems" or flags for both voices are up and collide where the "stems" for the lower voice should be down.

\version "2.11.20"
clm = \relative c'' \repeat tremolo 8 { e16 cis }
clma = \relative c' \repeat tremolo 8 { e16 g }
\new Staff {
  \clm \clma
  << \clm \\ \clma >>
}

When applying tremolos to whole notes, it's nearly impossible to print the tremolo beams _under_ the notes and not _above_, like demonstrated in snippet LSR 241

This is a related bug, but IMO we definitely should mark it as a Defect (rather than an Enhancement).

\relative {
  \clef bass
  <<
    {
      \voiceTwo
      %this doesn't work (a whole note has no stem):
      \stemDown
      %strangely, this doesn't work either:
      \override Beam #'direction = #DOWN
      \repeat tremolo 16 { f,,32 c'32 }
    }
    \\
    { \voiceOne r4 d8 d d2 }
  >>
}

Regards,
Valentin.

This works just fine:

\relative c'' {
  \stemUp
  c1:16
  \stemDown
  c1:16
}

Valentin, please create a minimal example which demonstrates the bug.

In support of making slanted tremolo "beams" for whole notes the default behaviour, some elements from a discussion of February 2010.

Basically Werner, Reinhold and Han-Wen agreed that slanted "beam"
tremolo should be the default behaviour for whole notes.  And Reinhold
said that

"According to Gardner Read (p. 236-237) and Kurt Stone (p. 150-151), the beams of whole-note tremolos are slanted like with shorter durations with stems, but the beams are placed centered between the whole notes (i.e. not where an imaginary stem would end!). The only situation where an imaginary stem is used to determine the position/slant of the beams is in cross-staff tremolos."
