Add the ability to mark the chart

I would love to be able to drop a gold star or something on the graph to mark the places where I have talked in my sleep. Also, why do I have to have a nickname – and even worse, an original nickname – to enter review? I type it out, it tells me the name is taken, and I lose everything I have written. Really stupid.
