A couple of thigs I do carry not on the list are a Pee bottle ( a wide neck nalgene, carefully marked!), its the nearest you will get to an en-suite in a tent, and as you get older....... it makes the tea in bed in the morning possible for me anyway.
I also carry a trowel - one of the back-packing light orange ones, you already have the tissues and hand gel.
