Request for a focus mode feature

We know a lot of people face distraction due to social media and other apps. And somehow adding a focus mode to restrict the use of apps will address it. Bring it on two modes.

1) App restriction mode ( restricts the selected distracting apps ) for a defined timer .

2) Full restriction mode ( restricts the phone completely) for the timer ⌛ set.

a) normal mode - can exit the timer.

b) strict mode- can't exit the timer.
