It does :)

The part I omit is the voltage source. All currents I need in my
system flow from plus to ground.

Yep, because I largely don't have any here, only in few special
cases (where I also can use some kind of "current priority").

Wow ... Overkill :)

I once looked at this, but couldn't find out how to use it with my
problem. :\

Those are all a bit daunting ...

Thank you for the offer. I'm presently having problems understanding
even the examples, so I'll call in if I get so far.
