We took a bit from the mixed columns and single +%D column page code. This one works acceptable with floats and is for whole double +%D column documents. We don't balance (yet). Footnotes are per column. One can have +%D side floats too. No balancing and other fancy features. +%D +%D Don't use this in production! Although the main approach will stay there might be +%D changes in the way floats are dealt with. Not much testing has been done but as +%D we stay close to the single column mode we expect most to just work. Only floats +%D are the (usual) pain.
