the way things are arranged in the inventory looks like files in our computer that we copy in various folders, so to have different oufits we copy the item to all the different outfit folders.
why not saving the outfits like playlists, like when we play some mp3 in a media player, is just a text file of songs in different folders.
like
---------------------------------
c:\music\song1.mp3
c:\music\album\song2.mp3
c:\other\song3.mp3
---------------------------------
result:
---------------------------------
\body parts\hair\ponytail
\clothing\denimpants
\objects\watch
---------------------------------
it will save space on linden lab servers by not having various copies of those items, replacing it with just a text file, and also we will have our inventory cleaner.
