Several of the missing capabilities mentioned here can be done with 3rd party tools.

* BetterSnapTool for window snapping and maximization (although I prefer Moom for better control).

* Afloat to force a particular window to always be on top.

* TinkerTool to mess with various other settings.

Sure, these may not be “built-in” as first party capabilities, but Apple has a history of slowly bringing such capabilities into the OS over time. Flux (for altering screen tint at night time) became standard. So did TextExpander (for auto-expanding abbreviations).
