13. Projects, saving and recovery

Ctrl+S saves, Ctrl+Shift+S saves as, Ctrl+O opens, Ctrl+N starts fresh.
A project is one .nebproj file. It is JSON, versioned, and carries a copy of any samples it needs, so it can be moved to another machine.
Autosave: while you work, Nebula writes a recovery copy. If the app is killed, the next start offers to recover the unsaved work — your saved file is never touched by that.
Backups: each save also rotates up to a few older copies beside the file (name.nebproj.bak1, .bak2, …), so a bad save can be undone even beyond the undo history.
Unsaved work: closing with changes asks first.
