Things is my main task manager and I’d like to keep using it. It would be great if Today tasks or tasks with a certain tag or category could go into Slash.
Unfortunately Things doesn’t have an API. However, I specifically coded our copy/paste function to work with Things. If you select all your tasks in Things and hit ‘copy’, then paste into Slash, it should import them perfectly :)
It appears this is possible via AppleScript (albeit not easy), but I’ll leave this here for the future:
