Maintaining folders in thread order with incremental updates is
*very* difficult, AFAICT.

I realise sequences are effectively unordered; my suggestion was for a
*hierarchy* of sequences, i.e. multiple sequences to reflect (some of)
the threading information. Listings of subthreads would still be done
using spin by giving it a sequence, for instance, but having a
hierachy of sequences means thread navigation would be possible, i.e.
the thread navigation consists of moving from one sequence to another,
using the sequence name itself to determine where to move to.
