Developer / company: A Sharp, LLC.
Opal lets you organize just about anything — ideas, reports, lists, notes, projects, graphics — in the form of an outline.
Opal’s elegant, uncluttered interface stays out of your way so you can capture notes efficiently. You’re free to organize — and reorganize — however you like. You can always find information later, using fast filtering or Spotlight. Or keep it out of your way by shrinking long topics or focusing on part of a document. Prioritize lists with flexible sorting. Track projects with smart checkboxes. Multiple selection lets you work faster. Streamlined and responsive, Opal is truly your digital notepad.
Opal will be familiar to anyone who ever used the popular and reliable Acta outliner. However, it’s completely rewritten for Mac OS X.

Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program.
