Just as I can with Actions, I would like to suggest adding the ability to define a separator entry in an outline. This would display a standard horizontal line (similar to a HTML horizontal rule) as a way of separating/grouping outline entries at the same level.
Why The Need:
The Notes 8 Mail template is now able to display separators in the mail outline by virtue of Eclipse.
IBM's User experience guidelines for IBM Lotus rich client applications defined the characteristics for separators
BUT as a Note developer I cannot easily create a separator in an outline.
