KISS. I love it. It's a input bar. You get the history when you click on it. It's common to find whatever you want to do here. You also get favorite apps bar. You can search contacts, wikipedia, shortcuts (awesome with http post shortcuts or chrome webpages shortcuts). Contacts have a sms/call button on the side and they also appear on the history list. I use it on all my phones. It's lightweight, open source and half my friends don't know how to use my phone.
