Comparison
Superdock vs DockDoor
Short answer. DockDoor is the app most people find first when they want Windows-style hover previews on a Mac. Choose Superdock if you live in several Chrome profiles: DockDoor cannot split them because it does not own the tiles.
DockDoor is the app most people find first when they want Windows-style hover previews on a Mac. It leaves Apple's Dock in place and draws previews and an Alt-Tab switcher on top of it. Superdock replaces the Dock with an identical-looking one so it can change the tiles themselves.
