It will be good to have 2 "do not disturb" options.
Need 2 types of ringtone settings with timings. So that we can use separate ringtones for day & night! Day ringtone will be louder and Night one will be less louder.
"OR" we can have options to choose the ringing volume for day & night! Day volume will be louder & night volume will less louder for the same ringtone (with manual timings).
