OmniFocus AppleScript to move an action to my "❌ Dropped" context and mark it completed.

Drop Action.scpt

-- Drop an action
--  Mark it "Complete" and add front tag of "❌ Dropped"
--
tell application "OmniFocus"
	tell front document
		try
			set droppedTag to first tag where its name contains "Dropped"
		on error
			display alert "No tag found whose name ends with “" & "Dropped”"
			return
		end try
		tell content of document window 1
			set taskList to value of every selected tree
			repeat with aTask in taskList
				-- mark dropped, then mark complete, if it repeats remove droppedTag
				add droppedTag to front of tags of aTask
				mark complete aTask
				-- When the task is marked complete and if it is a repeating task
				-- the repeating task is copied and then marked complete (carrying the
				-- dropped tag with it.  The remaining task is moved to the next time
				-- and the dropped tag should be removed from it 
				if repetition rule of aTask exists then
					remove droppedTag from tags of aTask
				end if
			end repeat
		end tell
	end tell
end tell

Changed line 16 to use new (2.12, 3.0Beta) AppleScript verb with mark complete aTask instead set completed of aTask to true since the completed property has become read-only.

Update to OmniFocus 3 where there are tags instead of contexts

Added logic so that any repeated item (which is actually the original modified) does not have the drop tag.
