Maybe I'm using it wrong, or its mentioned somewhere in the docs, and I have not read it properly.

But if you do this :

user = User.first
$rollout.activate_group(:chat, :all)      # You'd assume this activates feature for everyone, and it does.
$rollout.deactivate_user(:chat, user)  # I'm assuming this should only deactivate the feature for this user, everyone else should still have it acti

Would be nice to be able to use this with Swift/Cocoa APIs that accept a fraction Double.

For example:

• https://developer.apple.com/documentation/uikit/uicolor/1621922-withalphacomponent
• https://developer.apple.com/documentation/appkit/nscolor/1526906-withalphacomponent
• https://developer.apple.com/documentation/swiftui/color/3049763-opacity
• https://developer.apple.com/documentation

Involves running and recording different configuration in the sample app, and adding the visual representation of the behavior to the readme file.
