OK, understood. I have not yet found any usecases for this yet.

in GRASS-terminology this is called 'layers'. yes, understood too. But
I thought this goes to a different tables (linked to different
'layers').

The different 'layers' are very powerfull indeed, but I think I do not
get it right here in the use with QGIS. I thought this is done through
the 'layer' selector in the edit-dialog.
