Mission Control (macOS)
Mission Control is a feature of the macOS operating system. Dashboard, Exposé, and Spaces were combined and renamed Mission Control in 2011 with the release of Mac OS X 10.7 Lion. Exposé was first previewed on June 23, 2003, at the Apple Worldwide Developers Conference as a feature of the then forthcoming Mac OS X 10.3 Panther.[1]
Operating system

Mission Control allows a user to do the following:
Mission control evolution[edit]
Using the Shift key, Mission Control can be activated in slow motion, as can Dashboard and the minimise effect and several other animations. This is the same effect that was demonstrated by Steve Jobs during the unveiling of Exposé during the 2003 Worldwide Developers Conference.[5][6]
Similar alternatives on other Operating Systems[edit]
Similar effects are used on other operating systems.
Microsoft Windows 2.0 first introduced a window switcher in 1990. Using Alt+Tab ↹, users could see a flattened view of all open windows. Every version of Windows since then has also provided this window switching functionality. Vista and Windows 7 provide an additional feature called Windows Flip 3D, which has a broadly similar purpose. Flip 3D allows a user to flip through all open windows with a three-dimensional perspective. A downside to this method is that the front-most window covers a significant portion of the other windows, unlike Exposé. On the other hand, this allows the user to see the contents of the front-most window, while this can be difficult in Exposé, especially if the user has a large number of windows open. Vista's Desktop Window Manager exposes a public API that allows any application to access the same thumbnail representations that Flip3D uses, and so there are a number of third party add-ons that are able to provide Exposé-like functionality in Vista. A very few third-party applications, such as the Emcee Desktop Organizer, provide Mission Control-like organization of similar windows into visual "stacks," or support Windows 8's "Immersive" Apps. Windows 10 adds a very similar feature called Task View which also includes multiple-desktop support.
Microsoft's Intellipoint Software for Microsoft Mice has a feature similar to Exposé[7] as it also works with live images of windows, rather than static representations.
Microsoft's Windows 7 introduced a feature called "peeking" that allowed a user to hover their mouse over an icon in the taskbar to reveal a small thumbnail depicting the contents of the application's window or windows.[10]
Compiz and KWin are compositing window managers for systems using the X Window System. Both include plugins similar to Exposé - the scale plugin in Compiz and the present windows effect in KWin. Skippy also performs similar functions to Exposé.
Starting with version 3.0, the GNOME desktop environment has gained a new mode called "Overview", which is used to launch applications and manage workspaces. In this mode, windows are scaled and arranged in an Exposé-like fashion for quick switching.
For Classic or Legacy Macintosh systems, the free Finder Workspaces[8] offers functionality similar to Spaces.
ChromeOS has a window overview mode[9] that shows a thumbnail of all open windows, available by pressing the 'window switcher' key or swiping up with 3 fingers on the trackpad. Windows in overview mode can be closed by clicking an associated close button, or selected by clicking on the window thumbnail, which also closes overview mode and brings the selected window to the foreground.
