There are 2 features I'd like to see, and would like to code (would be my first java app ever!) 1) since most of our new calendar events are to meet with/call people in our contacts list, id like if the context menu for contacts could have a menu item added: Create Event. what would happen when selected is a new calendar event window would pop up, pre-populated with the contact's phone number in the Description field and their name in the Event Name field. the user could then modify these to add details. this mod would save us from having to go to the calendar and create an even to "call joe", only to have the reminder come up later and then have to navigate the contacts to find joe so we can call him. here, the event would have his number preloaded and could be clicked on (like a hyperlink) to load the number into the dialer how do we hook into the contacts.apk file to make this type of mod? or, is the mod to be done some other way? 2) though we can select different ring tones for different contacts/groups, and we can also set different ring volumes/vibes, it would be nice to have a ring profile that would, say, only let the "family" group ring but stay silent for everyone else. this way, i can put the phone in this mode when going to sleep, but still be available for emergency family phone calls. i've searched around on xda and the google android developers group, but didn't find what i was looking for. any ideas?
