You can, but note that Agenda isn’t supposed to take over as a task manager. So you’ll find limitations if you compare them.
That said, I do a simple combination of tags and smart overviews to keep track of things. (Note that this was my past workflow. I’m currently exploring the agenda->reminders->OmniFocus integration)
The basic concept is to add a #due(date) and one other tag for tasks. If it’s a stuff I should do, I tag it as #open. If it’s someone else’s task, like a colleague or a direct report, I tag it as #waiting.
- Send email blast to XYZ #due(tomorrow) #open
- Ask @john about ABC #due(monday) #open
- Did @martha finish uploading the PDF? #due(tomorrow) #waiting
Then, I have smart overviews for the open and waiting tasks. So I just look at those.
Downside is it contains the entire note.like a meeting note can be 50 lines. With 5 tasks in it. This is the limitation I was telling you earlier.
Once the task is done, simply remove the open or waiting tag and the note will disappear in the smart overview.
Additional workflow: if a note has no tasks left, and it’s something I don’t need to look at again, I mark it as done and collapse the view so it stays out of my view.
Last comment: others do copy/past of tasks and linking to original notes. I tried that but it’s very cumbersome. That usually involves having a project with all your tasks hyperlinked to other notes. In order to get context, you click on it to see the original note. Then go back to your main task list. Too much clicks for me so I abandoned that. But it’s cleaner and helps you track your tasks more like a task manager.
But again, agenda isn’t a task manager so you can’t expect it to function like a complete replacement. You’d have to adjust your workflow. Good luck!!
