Starboard pins a genuine zsh -l shell — real history, working directory, state — permanently beside your Dock, tracking its height and position live across every Space, including over full-screen apps, without ever stealing focus. Cmd+E expands it to full height when Dock-height isn’t enough. The whole app is under 700 lines of Swift, MIT-licensed, and ad-hoc signed rather than notarized, so first launch needs a manual click through Gatekeeper.
