[Feature Idea]: Scale/Chord/Tuning datasets/tags.

[Sintrastes]

Currently, regardless of origin or characteristics (e.x. for a scale, MOS v.s. traditional v.s. MODMOS etc...), all scales, chords and tunings are lumped into the same category.

It would be helpful if there was some notion of "dataset" or "tag" that would allow the user to more easily filter out data that is interesting to them.
