DSH composer plugin: an expand button that turns the input into an immersive overlay writing surface where Enter makes a newline and only the send button submits.

DSH plugin: type or paste anywhere in the window and it lands in the current conversation's composer — no click needed.

Polish the DSH left sidebar: drop the brand row, redraw New Session as a panel row, unify row heights, tune the fill, pin the collapse toggle, add a settings entry, mark idle sessions.

Pin the New Session composer to the exact place the conversation composer occupies, so the input box stops jumping after the first message.
