Ask HN: What should Apple add in the next Mac OS X 11?

A few articles have said they've denied it (which probably also means their working on it) - Universal apps across all devices

1 app that works across all devices - laptop, desktop, iPhone, iPad and Apple TV if it's warranted. With app thinning, it's completely possible and when the Ax chip gets fast enough to appear in laptops / desktops (another generation or 2 away IMO) completely doable.

With this, give OS X developers a UIKit (another missing / requested feature) and whatever else is missing to make that happen.

Isn't the X part the number 10?

So it would be Mac OS XI :)

Windows Power Management in Mac

X11 support. Would be apropos.
