  • Clips Grouping: When used in ARA mode, you can choose to group imported clips sharing the same format into a single project (default behavior in SpectraLayers Pro 7 and earlier, best suited for music production) or import each clip into separate SpectraLayers Pro projects (best suited for post production).

  • Maximum History Actions: Maximum number of actions to show in the History Panel.
  • Realtime Brush Preview Limit: Maximum number of samples a tool can handle for its realtime preview.
