Preset variations / versioning

[Trinitou]

The addition of the set_timestamps method for presets in (see PR #270 ) made me think about a versioning/variations feature for presets. I think it would be a great feature if as a sound designer I could have multiple versions/variations of the same preset.

• E.g. if I modify a preset from a soundpack, I want to be able to customize it but still keep the original.
• I pretty often save intermediate preset versions when working on presets. Helpful for comparing later if I improved the preset or not.
  • So I often end up adding number suffixes to the preset name and end up with a lot of presets called 'Ultimate Bass', 'Ultimate Bass 01', 'Ultimate Bass 02', ...
• Or if a soundpack get's an update and some presets got modifications, the soundpack creator could make use of preset versions.
• With preset versions/variations a preset browser could show them as a single preset but with multiple sub-presets. (with the latest/newest variation as the parent node). Or maybe let the user decide via an option whether to show older preset versions or not.
• But maybe it could be allowed to define multiple presets with the same subpath/load_key but with different timestamps???
  • (ATM the definition says subpaths have to be unique.)

It's only a rough idea. What do you think?
