it isn't clear what many of the options do. It would be useful if there was a verbose description of what each controllable function does. For example when you hover it in the drop down list, and when you hover a button that has it set. There should be an area that displays those descriptions. I think this would be useful for many features of the UI, sometimes it's not clear what the settings or sliders do, and a few sentences would go a long way towards helping new users figure things out.
