New, but kinda pointless
It is a cool idea if getting to links wasn't already so easy to do everything. Double clicking this or double clicking firefox doesn't really make and difference in time at all. And why do you need a clock when every OS has a clock on it?
Make the program have some other features, like opening programs that are used a lot, or opening specific files used a lot (like play-lists, games, applications, etc. etc.) Then it may be worthwhile.
