I appreciate this is tough. However, given the existence of UCSC-like
"super-sources" containing basically unrelated types, with potentially quite
different densities and dispositions, I find it hard to see how this is
going to be useful without some kind of interaction with the types filter
along the lines of what I've proposed.
