Opal is an outliner. It lets you organize just about anything - ideas, reports, lists, notes, projects, graphics - as an outline. It stands out for its uncluttered, fluid interface. But Opal includes features not found in other organizers:
  • Shrink a topic to a single line
  • Alphabetic and numeric sorting
  • Magnify on-screen text
  • Word count
  • Focus on part of the outline
  • Multiple selection
  • Link to other documents
  • Just create notes - no need to name them
  • Open Acta outlines
  • Spotlight search
  • Topic filtering via toolbar Search field
  • Smart checkboxes automatically track completion
  • Open or more...
