Game-profile editing is now substantially faster and easier. Click selects one 16×16 cell, drag paints a continuous selection without skipping crossed cells, and Ctrl+click or Ctrl+drag adds/removes cells. A single class and label can be applied to every unique selected pattern at once, with duplicate patterns automatically deduplicated. Selected cells and the active cell have distinct highlights, while Esc and the new Clear Cells button clear the selection. Bulk common-pattern warnings and automated additive/drag-selection regression coverage are included.
