In the Trends page I often want to jump between the same time period on different days or between time intervals on the same day. I was able to implement back and forward buttons on either side of the Day and Time selections using a Greasemonkey userscript, which basically selects the appropriate option in the "drop down"s. I have been using this for over a year and thought that I had already submitted the idea. I think this would make a great addition.
