Worm Face allows you to pick/drop textures on the faces of objects in your scene without having to go into sub-object mode or edit Multi/Sub-Object materials. Currently picks from any object but only drops onto Editable Poly.
I built this tool to emulate the same features in the Texture Application Tool that is in Hammer.
Thanks to denisT on the Area forums for insight and sample code to pick faces in the viewport.
