its a nice concept and a nice idea but its too complex for what you want to do.
1) you have to hightlight the text with the browser before highlighting it with the marker
2) rather than the marker be right where you are, you either have to hightlight the text with the mouse the right click on it to select the marker or use the wired-makrt thing at the top.
its a good idea but way too complex to make it for general use. you should be able to select the highlight without having to highlight anything and you should be able to choose the color instantly without taking all those steps.
