In Lumiera, "Tracks" are not what you'd expect from conventional video editing software. They are a mere grouping devide, and are also used to implement the "media bins" and tool palettes. But having "folders" on the timeline would be likewise confusing, as would be to have a "branch" or "tree". To get out of that dilemma, we chose an understandable but deliberately somewhat strange name: "Fork" It was common understanding on the Mailinglist that we should handle this renaming in a tuned-down and discrete way: The UI will continue to show "Tracks" for a familiar sight and "Bins" in the Asset section. But Lumiera developers will be nudged to accomodate by renaming the entity in source code accordingly
