To be honest, while annoying and I hate it, I can tolerate the bigass layout of the Wishlist.  The functionality is what kills me-- the "sort by" functions don't work (clicking does nothing) and there is no option to sort by vendor.

The bigass layout of the MP however is something that I cannot tolerate, and makes the MP unusable for me.

 

Tim said that the small and large thumbnails are due to the fact that some vendors have not submitted the new thumbnail size. Were vendors not informed in time to make these changes before the opening?

*It only matters to a limited extent, really.  Some vendors simply are not active here (and some are not active in the 3D world at all anymore).  I doubt those vendsors are going to drag themselves here just to make bigger thumbnails.  So the different sized thumbnails, while it will become much less significant, is here to stay.
