As an old-school outliner from PC-Outline days, I always preferred the '+' and '-' symbols for collapsed and expanded entries. Fortunately it's easy to achieve this in OO and OOP, as follows (note, please make a backup copy of the original files just in case...)

- Right-click on the OO or OOP application and select 'Show Package Contents'
- Browse to Contents>Resources
- Copy the 3 files attached to this post into the folder, replacing the existing files
- You're done!

Now when you open any outline it will have the '+' and '-' symbols, which (IMHO) improve the whole look of an outline. You can also change the Text and RTF export preferences to export plusses and minuses too.

Of course, whenever you update the application it will revert back to the standard symbols, but it only takes a few seconds to reapply this trick.
