One thing I noticed after reading through the Online manual is that there is no Homepage return link. It a very small thing but it is somehwat handy as then you can just press the button to return to the main site rather then click back a bunch of times to get back out of it.

ever tryied clicking and holding on your back button in your browser. It shows you all the links you've recently visited. You could simly select the original home link there and your done. No need for a back button in the page it's self.
