 ### Fixes
 
+- **Control UI terminal tabs:** vertically center the new-session button in the terminal tab strip.
 - **Control UI composer scrollbar:** show the message-field scrollbar only when the draft actually overflows its autosized height.
 - **Control UI terminal cursor:** hide the browser-native contenteditable caret so the integrated terminal shows only its canvas-rendered cursor.
 - **macOS SSH tunnels:** resolve user-installed SSH `ProxyCommand` helpers through the app's managed PATH while preserving inherited connection environment, so remote aliases work after Finder and sanitized-script launches.
