Editing in the timeline is the most common workflow inside Zrythm. The timeline section consists of the tracklist on the left and the ruler/arranger on the right side.
At the top of the tracklist, the number of visible tracks over the number of total tracks is shown, as well as a search box for searching tracks by name (not operational at the moment).
The rest of the tracklist is briefly touched upon at Tracklist.
The tracklist is split between the pinned tracks at the top and the unpinned tracks at the bottom. You can pin tracks to make them stick to the top, and this is useful for chord progressions and markers, so you can always see them.
For more details about track operations, see the Tracks section.
This section contains the timeline events and various ruler markers. It is similarly split to match the tracklist on the left.
