[Feature Request] Recording only calls from or to unknown numbers
I'm not sure if it's easily possible, but I'd suggest to implement an option to record calls only from numbers that aren't already stored in a phone book.
Why: because if I call my mom or my friend or anyone from my phone book I don't really need to record such call. Otherwise I need to still remember. For instance: Okay, now I'm calling my fried I should turn off recording or at least recorded file after all.
PS: Anyway, thank you for your work and nice application :-)))
