Bernd,

you may have seen the pin definitions in the eeschma help document it's
quite extensive. 

Most of them are fairly obvious, and you choose from them as needed. It
is the pin assignments that DRC uses to The danger of using undefined
and so on is that drc will then not work very well if at all. However
for things like connectors, then passive is a reasonable choice.

The ratsnest of the wires, that's another matter You can of course
limit what you see with the show general and module ratsnest options,
but the main problem is that Kicad will not know which pin the main
board trace will connect to until you actually connect it. Hence ypou see
the ratsnet. A small case of chicken and egg I'm afraid.

As for the sheet name, well the docs do refer to this function, noted as
not implemented, but the docs are for a rather older version, so it looks
as if this idea has been thought of, but as far as I can see nothing
has been done with it.
