Accessibility
With Accessibility, Dock Ultimate finds the windows of other apps and can move them or change their size. Magic Switch, a chosen display for new windows, keeping windows clear of docks and the window switcher need it; the notification counters from the macOS Dock are read this way too. These features are in the direct edition only.
