Add an outlet to the end of a partially-switched circuit
Right on the money!  

You might consider running /3 cable anyway.  Every bedroom in our house has a long extension cord circumnavigating the room because the switched outlet (instead of a proper overhead light) is not in the roght place for how we fit out the room. You can just cap off the unused red wire. A future use of the room could swap wires so the switched outlet is in the new location and the present outlet is all unswitched.  The hard part is getting wire into the walls!
