Trying to set up OF so I can click on a task, and have it link to a checklist in OmniOutliner. Seems like it should be easy to do, but I haven’t been able to figure it out.
The easiest way is to just drag the file icon into the notes field of the task. That just stores a link to the file.
If you want to embed the file into the task, again, drag the file in, but whilst holding the option key.
