Here is an example of the ui.html using Bootstrap and some jQuery, (and jQueryUI just for the colorpicker). Showing Buttons as the radio buttons, clickable help icons and added a way to actually see the color selected in the colorpicker. Also, showing what a dropdown list might look like.
I'm happy seeing you experimenting with this! I noticed that the spinner buttons are no longer present though and the slider looks less good than before. Nice to see the help buttons and jQuery color pickers. I did however notice that the jQuery color pickers don't seem to remember the alpha.
