This looks like great work by Richard, a brief look at the list of plans has
already got me excited about what new splices he may have uncovered!

I definitely think the inclusion of those plans which cannot be joined up
into extents would be worth the effort, they could be used either for Bankes
James style arrangements or other types of multi-extent blocks.
