- Enabled fullscreen overlay rendering for the terminal session picker. - Implemented full mouse support including wheel-based scrolling and click-to-select functionality. - Anchored the session picker footer to the bottom of the viewport to correct UI flickering. - Added comprehensive unit tests for mouse interaction and layout constancy during resizing.
