Has there been any new changes in allowing a notification to come through when phone sound is turned off at night. (such as from work, family) The alarm function works fine when the phone sound is off. Is it too involved for programmers to change this? I have no programming experience.

I use google calendar on my phone. Is there any way yet to only display certain hours on the screen. Eg: 6:00am-9:00pm instead of the default of 12am-11pm. I know there are other settings;day, week, month, agenda.

Thank you.
