(OmniOutliner 4.6.1 for Mac)
I have one column in my outline which shows the creation date of that row. I put the dates in using Edit -> Insert Time Stamp -> [one of the formats], or using the equivalent keystrokes.
I tried Organize -> Sort Outline -> [that column], A-Z … and discovered that dates are just text, and hence sort alphabetically, which of course is useless!
Is there a way to put in dates as actual dates (i.e. correctly sortable, and not just text)? Failing that, is there a way to change the date format to YYYYMMDD HHMM (24-hour format) so that when sorted alphabetically they will also be sorted chronologically?
