What would be easier would be the ability to draw custom pad shapes with
multiple drill points. That way there would only be one pad number to
worry about.
The dream for me is to have the possibility with the module
editor to add tracks (as in the board editor) AND dummy pads. I mean pads
which are treated as tracks not as numbered pads.

I agree, my junk box is the same as everyone elses :-) However Kicad was
not designed as that sort of program. So we have to workaround things as
best we can. There is a lot of development going on with Kicad, so lots
of improvements are being worked on. The next beta release looks like it
will be fairly soon, but if not you can play wit the nightly builds if you
want to. As kicad develops I would expect that there will be some easier
methods to add multiple pads developed.
There was some discussion several months ago regarding some components
that have more than one power pin, This was a solution to some noise
issues I think by the component manaf. however two power pins caused
quite a but of confusion. So at least that sort of problem has been
flagged up. I don't know if there is any solution to this so far as I've
not been taking the nightly builds. If anything has been done then that
might help.
> Of course. This would eliminate some other similar Problems ocouring with
components which have more than one pad per connection. Worst i actual have
is a screw terminal with ten pads in two rows, all the same
connection.......:-)
That should not be an issue really, give each terminal pad it's own number
and also create a connector part with a matching number system, then
connections you make on the circuit diagram will be reflected onto the
module, including any multiple connections.
I have some terminal blocks that already have one side parallel
connected, with the other side for wires. i.e. it forms a bus-bar type
connection. Each pad is numbered differently and on the circuit I just
make sure I parallel connect all the pins, that keeps everything happy.
> An other point would be a TO-92 footprint wich allows stright and molded
Types. I saw it so often, but seldom you get a layout program, which allows
this......
That's more difficult - you can end up with clearance issues and it can
make track routing a bit awkward.
I tried that some time ago and in the end I decided it was easier to
simply have two footprints. :-)
> I am thinking, more than one pad per connection would create an logical
problem for DRC. Perhaps there would be a way to let the DRC recognizing a
(well declarated) group of pads as one pad?
What would be easier would be the ability to draw custom pad shapes with
