Using spatial memory to launch and switch apps in macOS creates a surprising productivity boost. Charmstone is a unique but simple spin on cmd+tab & the dock that easily fits into your workflow. It's especially great if you hide your dock.
SwitchGlass adds a dedicated application switcher to your Mac. You can customize its appearance, size, and position on each attached display. Use it to bring one or all of an app’s windows to the front, or as a drag-and-drop target to open files.
