After playing with it for a few days, I decided that I just really did not like the Sneak-Thief. As such, I have replaced it with the Acrobat. It has some of the similar elements but combines the Acrobat archetype I was developing into the class itself, removes one ability, and changes the skill list. I'm much happier with it now.
I also added the Trapsmith archetype and fixed a few formatting errors throughout.
