Outside of dedicated notification areas, a GUI should only change state in response to user action. Because the user requested the state change, they naturally know how it changed. This means any animation is a redundant waste of time.

The notification area doesn't need animations either, because a GUI is only appropriate for displaying non-urgent notifications. If something really needs urgent attention, you need alarms and flashing lights, not an animated "toast".

This is the standard confusion HNers have with real life.

I think it should work this way vs “how it be”
