One thing I love about my default Android Text Messenger App is I can set a SMS to be sent a future date and time. Something similar would be nice to see in the future builds. The ability for a message to get sent to the server and then the server hold on to it until the time comes to release the message or something like that.

This sounds like a great feature. I will definitely add it in the next feature development cycle.
