The live board stays beside seven main tabs. Use the position slider and navigation buttons to move through the game from any analysis tab.
Analysis compares saved engine results with the saved-results selector and keys 1–9. Position groups pawn structure, mobility, and king safety. Tactical and Annotations use textured sunken panels and gold-accented tabs. Read the saved-analysis guide.
Some screenshots below show earlier tool layouts. The captions and linked guides describe their current locations.
