I’ve searched here and in the docs; but can’t find how to add (in Dates on the right hand side) 1 day (or 1 week, or 1 month) to multiple Items in such a way that the existing (Due and/or Defer - it makes no difference) dates are respected.
IOW, I have a SAL Project with items due on (or deferred until) June 1, June 2, June 3, June 4 etc until June 10. Ten sequenced events; each one day later than the previous.
How do I add, let’s say, 1 day to all of them respectively, in sequence, so that they now become due on (or deferred until) June 2, June 3, June 4, June 5 etc until June 11th?
When I use the +1 Day button on (all the Events in) such a selection (where the first Event is due on (or deferred until) June 1), they all become due on or deferred until June 2.
Here’s a Javascript for Automation script from the awesome @unlocked2412 I am using successfully on macOS 10.14.5 with OmniFocus 3.3.2 Pro. It respects the dates of all selected tasks and will set due forward (or backward) relative to the current due date of each. The link above takes you to his original post in this forum. The code below is for posterity in case the other thread gets archived.
