If I may comment on that: I would suggest to document somewhere (in
the examples and/or the doxygen documentation) in more detail what the
difference between the various iterators is. When I was beginning to
use libMesh, this was confusing me a lot, and it took me weeks to
understand what "local" and "active" mean. In particular, I didn't
expect libMesh to still store the coarser elements after refinement.
I could imagine that other users have similar difficulties.
