Here are the release notes for the first version (0.9 because I'm sure there will be bugs!).
SMS Popup v0.9.0
- Show a popup dialog when a you receive an SMS
- The screen will wake up for a user defined time
- The secure keyguard will be disabled (only for the initial popup, after that you will need to unlock as normal)
- Close or Reply to the message
- If more than 1 message is pending an Inbox button is shown
- The Reply button calls the proper system intent, if there are any other applications available that can provide this functionality a dialog should show offering a choice of which application to use to reply. To use Chomp SMS make sure you have the latest version of Chomp (1.6) - previous versions did not use the standard intent filters.
