I don't like the fact that the "Call" and "End Call" are in the same spot. I prefer them being separate onscreen buttons so that I don't accidentally call someone when I hit the "End Call" multiple times. Is there any app for customizing this? Or, does this type of customization require a custom ROM? Second question: is there way to add a confirmation before any call is made?i.e. a popup that says, "Are you sure you want to call John Doe?"
