Further to the renaming thing: some character packages call the DAZ INJ and REM poses, and expect to find them in their be-!'ed folders. That's taking !! too far. Having said that, after I've removed all the merchants' !s I often rename folders and library items within the folders with !s of my own. The stuff that I use often should be at the top. For instance, I have a folder called !Copy at the top of most libraries, for temporary holding of items I want to copy between scenes.
