It would be really great if the Find list in OO iPad allowed the standard Find and Replace type selection - not asking for regular expressions and all that, just Find ‘this’ and Replace with ‘that’.
Copy lines and paste them in the document again would also be good whilst I am at it.
Well here’s a workflow that prompts for a search regular expression and replacement text and fires it at OmniOutliner. It’s pretty fragile, the regexp has to be valid and can’t mess up the JavaScript string variable.
