Film type (color negative, slide film, B&W) in metadata

I’d really like to have the option to sort my film by film type, so I’d find it super useful, if this feature would be implemented in the awesome metadata tool:

Film Type:

  • Color Negative
  • Slide Film
  • B&W Film

These are the main film types I’d need for my purposes, but feel free to add more, if there are any other ones, that some other people might need!
