I've got the next version of Sound Manager working. This one allows the user to set timers for the ringmode and vibration settings.
And, more importantly (to me), provides several intents for use by other applications. See http://www.openintents.org/en/intentstable
for available intents. (Sound Manager provides Ringmode Control, Sound Control, Volume Control, and Vibration Control.)
If any developers want to incorporate these intents into their app, you can email me or private message me for a free copy of the application to develop and test with. Just let me know what you'd like to use it for. (Sorry, I'm sure many of you would like this to just be out on the Market for free, but I can't keep stressing and making apps if I'm not supported for it, especially when sometimes I even put my real job on the line. I hope you understand.)
