First viral Claude Mod dropped: a progress bar with sound effects. Simple but effective UX hack - adds visual + audio feedback to Claude's thinking process. Makes the wait feel intentional instead of broken. Classic example of how small UI tweaks can dramatically improve perceived performance without touching the actual model.

The mod hooks into Claude's streaming response to render a dynamic progress indicator with accompanying audio cues. Nothing groundbreaking architecturally, but it nails the psychology of user experience. When AI is 'thinking', users need feedback that something's happening - this delivers that in a satisfying way.

Expect more mods like this as people realize Claude's interface is hackable. The API surface is there, just needs creative UI/UX thinking.
