There is a sub-editor for the bloglinks called `blogroll'
(in inc/bx/editors/blog/sub/blogroll.php with the xsl from
inc/bx/editors/blog/sub/xsl/blogroll.xsl). In this case,
the subeditor plugin generates the bloglinkscategories,
and you don't need to use a stream for that.

 but, oehm. i dont really get the scene behind that. i would like about 
a  similar "checkbox-list" for the links. Is it the best if i register 
an own "stream" and if yes, what are the steps to do so? If no, what 
would be the alternatives?


if you want to use a stream, you could create your own in
inc/bx/streams. The portlet stream is quite comprehensible
and easy to use as a template. All streams basically extend
bx_streams_buffer and have to implement a contentOnRead()
and a contentOnWrite() method. Don't forget to register
your stream with bx_global::registerStream($streamname);
before using it.

My guess is that if you can handle  input/output to/from your linkeditor
from within the same plugin, you don't need a stream. If other components
need to access your linksplugin (especially for writes), a stream
could be useful.
