Comment (by stumpc5):
> Sorry, I hadn't yet looked at quiver.py, and wasn't aware of all that
was in there. At a first glance, I'm very happy to see that this exists!

> I don't know what the rules/principles for organizing sage code are, but
it seems to me that the quiver stuff will be of interest well beyond its
cluster algebra applications. Should it be less hidden? Maybe quiver.py
should be a file in the combinat directory? Or maybe it should be
somewhere in with more algebra-related code?

people were aware of the quiver code in your patches, so the possibility
that it could escape notice is of some concern. (Maybe less concern once
it gets really into Sage, though, I guess.)
We had a discussion on quivers in cluster algebra and in representation
theory, see #12630. We decided in the end, that we will rename our quivers
for clusters to combinatorial_quivers (since they can be mutated and
stuff, which doesn't make any sense for quivers as input for path
algebras).
