Acta and Opal
Designer David Dunham says, “Back in 1986, I released an outliner called Acta. It ran on some of the earliest Macintoshes, and gained an avid following. It continues to run fine in the Classic layer. But Intel-based Macintoshes have no Classic, and many Acta fans were worried that they would be forced to stop using it. So I’ve created a modern successor to Acta.
“Opal retains Acta’s fluid ease of use, but is up to date with Mac OS X standards.”
Opal will be familiar to anyone who ever used Acta (or Dyno Notepad). However, it’s been completely rewritten for Mac OS X.
Some of the improvements over Acta include:
- Multiple selection
- Topic filtering via toolbar Search field
- Multiple Undo
- Auto-save
- Focus on a subset of the outline
- More keyboard control
- On-screen magnification
- Background colors
- Improved checkboxes
- Spell checking
- Mix Unicode text and graphics in a topic
- Auto-grow shrunken topics
- Read/write OPML outlines
- HTML output
- Extensive online help
But Opal still reads Acta outlines created over 20 years ago.
