Enrich operating system level user interface

Use case name

Enrich operating system level user interface.

Submitter(s)

Thomas Steiner (@tomayac)

Motivation

Enrich operating system level user interface with native-looking but flexible elements without requiring changes to the underlying operating system code.

Stakeholders

Apple (Since they use this, but I note that I barely document the use case, not speak on Apple's behalf.)

Analysis

Via @jimniels' blog post:

In the macOS terminal:

defaults write NSGlobalDomain WebKitDeveloperExtras -bool true
defaults write -g WebKitDeveloperExtras -bool YES

This will enable a context menu in a system web view:

Inspecting the web view with Safari's Web Inspector shows that it's using non-standard CSS properties and value keywords.
