A few questions about itemizations

A few questions about itemizations

[Marcin Borkowski]

Hi all,

this code:
%%%%%%%%%%%%%%%%%%%%
\defineitemgroup[subitems]
\setupitemgroup[subitems][each][a,packed][left=(,stopper=)]

\starttext

\startitemize[n]
\startitem
  Lorem ipsum
  \startsubitems
    \startitem
      dolor
    \stopitem
    \startitem
      sit
    \stopitem
    \startitem
      amet.
    \stopitem
  \stopsubitems
\stopitem
\stopitemize

\stoptext
%%%%%%%%%%%%%%%%%%%%

behaves differently if I change \startsubitems into
\startitemize[a,packed][left=(,stopper=)].  Namely, the vertical space
before (a) ... does not appear when using \startsubitems.  Why is that
so?

When I want to put the vertical space before the first subitem by means
of before={\blank[small]}, nothing happens.

Also, is \startitem ... \stopitem really better than \item ...?  (Apart
from the case when I use the [random] option.)

And finally: what is the difference between "right=)" and "stopper=)"?

TIA,
