Mixer sections can be collapsed in order to save space on the screen. This can be useful if the song contains a large number of tracks. Sections can be collapsed, and expanded again, by leftclicking the small button in the top-right corner of the section. While collapsed only the section's name is visible, all controls are hidden.
More powerful options are available if you rightclick (Windows) / Ctrl-Click (Mac) the button:
- Expand/collapse all sections
- Expand related sections only (appears on tracks and groups): expand all sections contributing to the sound of the current one and collapse all other sections.
- Expand/collapse same color tracks only (appears on tracks): expand all tracks having the same color as the current one and collapse all other tracks.
You can collapse/expand all same color tracks by pressing the Alt key while clicking the button.
