Yes. Good point. It's been in our mind for a while.

I've just made some changes that should improve this a bit.

Should be doable. Perhaps with a configuration section. Patches welcome ;-)

Indeed, abstracting the location in a future DB schema will solve this
problem.

Yes. But also it could be the same physical cable traversing a site.

The idea with site links was for the purposes of grouping circuits, yes.
The nearlink/farlink choice was probably a poor choice of database
representation, in hindsight. It should be undirected ideally.

No, in this case it was bad programming. I believe that this was fixed
in the last few days.

Well, closets are in rooms... but I agree. This is another one that will
be solved by the new "Location" object in the future.
Thanks for all the detailed feedback. We're constantly trying to improve
the tool.
