macOS Apps
RGB World, Inc has developed several macOS Desktop Applications including WindowMizer and Desktop Icon Hider.
WindowMizer replicates a macOS control panel named WindowShade which was originally introduced in System 7.5 and subsequently removed from the OS by Apple. The WindowShade Wiki chronicals the History of the WindowShade feature.
Desktop Icon Hider is a FREE macOS app that hides desktop icons and is distributed via the Mac App Store.
WindowMizer
WindowMizer is a macOS desktop app that rolls-up windows like a window-shade.
Simply double-click the title bar of a window, and WindowMizer sends that window to the Dock, leaving a placeholder title-bar on the screen. Double-click the title-bar again and the window is restored. No need to go digging through the Dock to restore a window you just minimized... it's exactly where you left it!
WindowMizer can be downloaded and used for 14-days – free of charge.

Desktop Icon Hider
Desktop Icon Hider is a macOS desktop app available for FREE from the Mac AppStore.
Instantly hide Desktop icons using a global shortcut. Display a solid color, a single photo, or a collection of photos from a photo album. Automatically changes images. Beautify your desktop by temporarily hiding all of the icons that seem to accumulate there. A simple keystroke gives you a completely clean desktop showing your favorite wallpaper. When you need to access a file on your desktop, the same keystroke will show the icons.
Now you see desktop icons...
Now you don't
