Here is a totally radical thought, that basically just represents thinking
Basic premise: a linear sequence seems antithetical to our tree-like model
of evolution, yet some of us desire that thearrangement of families relate
Would it be at all possible to arrange cabinets not in linear rows, but in
*clusters*??? Islands representing the various APG II orders? And the
allied clusters nmearer one another? It would probably be terribly
wasteful of floor space, but that might depend on the footprint
available. In some spaces, would it perhaps be a more efficient use of
space?? (I have a hard time conceptualizing in 3-D so I can't say.)
In any case, it might be something to consider, for folks who have rejected
the ease and convenience of the alphabet.
