Tektek layering doesn't always work out for me, (assuming it ever does) so I wouldn't like that very much at all =_=
Still, it's kind of sad that the whole layering thing is just that much more daunting. I mean we have an item-arranger that, while needs to be updated, it's still fairly easy to move items around. I figured a layering system would work something like that, only in our customize-avatar-thing...
It's just so frustrating to buy an expensive item only to realize that what you invisioned won't work. Ever tried a Yoko (from TTGL) cosplay, wearing the hair from Pistolera & Gold Ornamental Chopsticks? Doesn't work out very well v_v'
I wonder though, since the layering system is so complex as is, what if they just scrapped their current system and rebuild it into something more simple? Granted that would mean to temporarily disable avi customization, but seeing as how so many people want to be able to arrange items however they want...and we've been wanting this for so long, I think people wouldn't mind the wait XD
