I thought it might be a good idea to keep a running lexicon for Stage Manager now that Apple has seemingly named one of its components. As of macOS 13 beta 3, what I’ve been referring to as a “wing”, Apple now calls a “strip”.

• stage – a main area of a screen
• strip – a small left-aligned area where sets and windows live when they are not on a stage
• set – a user-defined collection of windows to be displayed on a stage simultaneously
• stack – a collection of windows and/or sets, organized by application in a strip, to be displayed on a stage individually
• stage manager – the mechanism that manages which window or set of windows is on a stage verses those that are in a strip
