Sorts Object Dimensions and place them left to right in order: Width, Length, Height, BBox Vol, Surf. Area, Spline Length
(of course, BBox Vol is not entirely accurate as a pyramid has pointy top so actual vol is quite small but BBox vol is large)
For Surface Area, all splines have 0, while for Spline Length, all non-spline have 0.
ver 1.01: added sort by Vert/Edge/Face Count and Footprint. Edge and Face count are useless to be honest...but it's there...Footprint is simply the area of the base of the BBox...so it will have inaccuracies too...like a sphere's footprint is NOT circular...
