Reference lines: - Side-panel cluster (ref_line_widget.py): list of lines with Add/Edit/Remove/ Clear and a properties dialog (value, colour, line style, tag) - Lines own their state as RefLineProps (held by MainWindow), drawn with a triangle drag-handle; dragging writes the value back and refreshes the list - Replaces the old centre-only add-and-drag-the-whole-line approach Comparison: - Time-axis mode selector: Absolute (seconds) vs Relative (% of each track's own length), so a long track and a short one line up by song position. Pure view transform (plotspec.apply_x_mode), no recompute - Overlaid different-length tracks now autorange their x union in absolute mode instead of clipping to the first track's span Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
