Sounds like you have 2 separate design questions. You won't find a
pre-packaged solution to either.
First, (to answer your first and third questions) you want to intercept any
hardware button presses in your main event handler before you pass the
messages to the OS. When you receive a button press, you can determine if
you want to ignore, pass it to the OS or hold on to it until later for
processing. There is an example in the KB for intercepting the buttons (I
think you can also look at the reptoids source)
Second, restarting your app where the user left off... Haven't done it
personally but you can use a DB to store the location where the user was
last (most apps use the unsaved preferences DB). The address book does
something similar. Take a look at the code. I wouldn't bother saving the
screen geometry and data, just where the user was last. Depending on what
your app is, the underlying data may change while the user is off doing
other things.
