DAZ started a unfortunate trend when they "invented" INJ morphs by putting the !DAZ folder directly in the Libraries folder.

If they'd put this folder one level down, everything would be much tidier.
As it is, pretty much every merchant that does custom morphs creates their own folder in Libraries which really clutters things up.

To move the directories contain the INJ/REM files would mean editing the paths in any files that use them, which would be impratical for the DAZ morphs, but would be possible (but mildly tedious) for single character sets.
