Notch improve for expanding screen and the other function adding

[NathanLin512]

Currently, when an external display is connected, you can’t see what’s happening in the notch—for example, to drag a file, you have to switch back to the Retina window—so perhaps a custom screen notch could be added.
Additionally, since most Mac users find the menu bar cluttered, I’d like to see if functions like “thaw” or “ice” could be integrated into the app; I think this is a pretty key feature.
