Support for selecting a video will come later.
Making this work was an absolutely awful time full of dealing with
delightfully kooky issues, and yielded in a very weird-shaped
contraption. There is at least one issue remaining wherein storyboard
videos do not actually display until the track is started in editor, but
that is 99% a framework issue and I do not currently have the mental
fortitude to diagnose further.
Users have asked for this multiple times since last release.
Not sure on the best default value, but I'm going with the
stable/classic one, at least for the initial release to avoid needing
migrations.
In the future we may reconsider this for new users.
This was another IRL request from a mapper / team member. The rationale
here is that it can be very annoying to map with break time enabled if
you have a large gap in the beatmap you are trying to fill with
hitobjects, as you are placing objects on top of a very gray area.
They will not only contract if the user chooses to have them contract
(new setting in the `View` menu) or if the game isn't wide enough to
allow full interaction with the playfield while they are expanded.
