Selective Notification App Idea

Hello guys👋,

Was wondering today about an app idea that would help people get rid of the FOMO we are constantly struggling with in today's world.

Selective notification system, an app that could block certain notifications for happening and show them in bulk when you want to.

Use cases:
You want to focus on a certain task, but you are waiting for an important message from your boss, you choose to only be notified if you get a message from your boss and other notifications are blocked.

You are in a group chat that has a lot of spam but also there are some people that sometimes give short announcements in the chat and you would like to be notified if that's the case.

What do you think?
