Simple -- an app that would allow more options for screen time out (between 2 minutes and 10 minutes -- say, 3 and 5) and also lock the setting. It is now 2 or 10 minutes and frequently changes by itself.
I'd like one that tracks and lists your communications with a contact (all of them, like sms, emails and calls) into a single timeline, with the sms and emails linked to the particular communcation. Like this:
Joe Smith: called 8/10/10 5:05 PM
Joe Smith: SMS 8/11/10 12:48 AM
