Ok - I was a bit harsh here. I think the problem is that the good ones
are buried in ones which are totally useless. I'm referring to the
ramps like the different country flags, multiple variations on black
and white stripes, and things like banded "christmas candy" ramps.
Maybe we should curate a list of good ones and only show those at
first, rather then the "all ramps" category.
