v0.0.2

Added

• Saving projects. Ctrl+S opens a file browser the first time; after that, or when you
  started mTrak with a project file, it saves straight to the same file.
• Save As with Alt+S, which always opens the file browser so you can save a copy somewhere
  else. On macOS this needs your terminal's "Use Option as Meta key" setting.
• File browser: move with ↑/↓, press Space to enter a folder or select a file, and
  Enter to save. With a file selected, Enter overwrites it; otherwise it asks for a name
  and extension and saves a new file in the current folder. Ctrl+N creates a folder and
  Esc cancels. Only folders and .mtrak files are listed.
• mTrak creates a projects folder (mtrak in your music folder, e.g. ~/Music/mtrak) and a
  config folder on startup. See the Config section of the README for the paths on each
  platform.
• Starting mTrak with a project path that doesn't exist yet (mtrak new-song.mtrak) starts an
  empty project that Ctrl+S saves to that path.
• Errors such as a file that can't be written or a missing MIDI system are shown in a warning
  dialog instead of crashing mTrak.
• Key hints in dialogs and the file browser scroll when they don't fit, like the main footer.
• On macOS, key hints show ⌃ and ⌥ for Control and Option.

Changed

• --color 16 is now --color ansi16.
• macOS terminals without truecolor support, such as Terminal.app, now get the 16-color theme
  instead of the monochrome one.
• Opening a file that isn't an mTrak project, is damaged, or was made by a newer mTrak now
  shows an error and starts an empty project instead of crashing.

Fixed

• The "GLB Velocity" key hint was misspelled.
• Building from source works again on Rust 1.85.

Known issues

• Projects can only be opened from the command line (mtrak song.mtrak), not from inside
  mTrak yet.
• Long error messages are cut off in the warning dialog.
