Well, I have the addon ported up to 7.3 now, I just need to figure out this issue with the markup panel (it's creating the popup at 0,0 vs just under the icon) then it'll be completed.
Ian helped me figure out the issue I was having; so it's all ported up to 7.3; so time to wait to see what Rick decides on inclusion (or for pub beta to start so i can post the addon at ubbdev)
