After doing some work related stuff using this "new" found knowledge... yeah, it's still not ideal. If the Large icon disappears due to the track being too vertically small it becomes a bugger to drag them again. It would be nice if the SMALL icons did the same thing.
However if the tracks aren't COMPLETELY minimized vertically yet the large icon is hidden if you hover around approximately where the large icon WOULD appear them you can reliably get the up/down drag arrows.
As far as my embarrassing story...
nope... it would take a while to explain anyway and I gotta get some other stuff done.
Maybe later.
