The notch overlay now has real concave corners that bite into the menubar bezel exactly like Apple's Dynamic Island. Apple spring physics (cubic-bezier(0.32, 0.72, 0, 1)) for all expand/collapse animations. Looks like part of the OS.
Entire UI rebuilt in React + Vite with Zustand state management. Faster, cleaner, easier to extend.
Bold, color highlights, and smart cue markers: [PAUSE] [SLOW] [BREATHE]. Format your script exactly how you want to deliver it.
Save multiple scripts, switch instantly. Auto-saves on start. Local only — no cloud, no account.
Pastel light mode default. Toggle from settings or the menubar. Persists across sessions.
Adjust scroll speed and font size on the fly — no need to pause your delivery.
Clean React settings view with auto-height. All preferences in one place, persisted across sessions.
