Thank you guys for your suggestions and support.

@datjomp: Never thought of such an use. Awesome

@Andrew_b: That's a good idea. As I see it, 'Unknown' callers won't be in your addressbook, so they should be blocked by default, when the app is running in that mode. In addition I will add in support for Unknown numbers in the blacklist if you want to accept all calls/sms except the one's in blacklist.

@figaro: Yes. I think I did

@droll: Great ideas! Had thought of providing time based activation myself, but moved it to version 2 as currently, using'Alarmed' you could set it to activate based on time. Profile based and Roaming based activation is an interesting idea, I would definitely try to do it now, or maybe in v2.

@yellowjacket: Caller based tunes are already supported by Crochik MyContacts
