I think I tried something like that on my one. It kinda worked, but there were still really weird sorting errors, at least on mine, not sure about Madsters. Not telling him not to try though!!
I'm thinking it didn't work on mine because, while I have a variable stating the 'fake height' of the BOTTOM edge of the objects, I never could figure out a good way to tie in the variable that I use to show the TOP edge of each object as well. Surely you guys have seen my example? I'll try and find my link just in case some of my code can help in any way.
Ah here it is:

I was trying a different idea for sorting in that cap, the original sorting that I fall back to when my ideas fail is in there too, just toggled off
