Hello Joerg,
thanks for the feedback. I will try to address your points in the following:

already possible: uncheck 'select edges' in delete model allows deleting
individual lanes

already possible: right-click edge and select 'split edge' or 'split edges
in both directions'. (not available in all editing modes)

already a ticket: http://sumo.dlr.de/trac.wsgi/ticket/2140. Right now it
may sometimes help to disable drawing of junction shapes altogether
(visualization options)

this is an old issue but wasn't a ticket yet:

This should already work. Also, if junction shapes are very small, a circle
is drawn instead to make it selectable. Since connections are currently
modified by clicking lanes there should be no problem. (However this might
become an issue when editing connection attributes in the future). Maybe
you can describe the current editing issue in more detail?

Being controlled will be an editable property (see
http://sumo.dlr.de/trac.wsgi/ticket/2067 which is being worked on
currently)

both already a ticket: http://sumo.dlr.de/trac.wsgi/ticket/831

This is a bug. Thanks for reporting (

I could not reproduce this. All plain xml files are saved in the same
directory on my side. Can you describe the symptoms in more detail?

Not sure how your idea would work but it might be covered by this:

This might be nice but possible the subnet-feature along with a library of
subnetworks would provide most of that functionality already (changing lane
numbers is quite simple already and getting a configurable-width roundabout
is already a ticket).
However, it could be worthwhile to add wizards for accessing netgenerate
functionality from netedit:

Thanks a  lot for all the suggestions. Keep them coming (-:
