Date Filter: Add Next and Previous buttons

For the date range filter at the top of every page, it’s kind of a pain in the ass to pull down the menu and select the next or previous day from the little calendar. What I would like to see instead are simple Next/Previous buttons that would load the next and/or previous date range (so if “Week” is selected, it would load the next/previous week, and so on). Obviously if there is no next or previous data available (for example, you’re viewing “Today”), then the links wouldn’t show up.
