metavirus, here is the mod you asked for.
Credit to deathbane27 for his ORIGINAL mod (Mook style)
Credit to any others that I may have missed.
My mod is a compilation of deathbane27's mook INV and depechenode's Advanced Inv mods.
Per request, my mod has been "mooked" up and ready to go as soon as approval from admins.
Screenshots explain details.
