While it can be a lot to manage, have you looked into using defer dates? You can sort perspectives by defer date. I’ve been using defer dates to plan my work for each day (but only critical work, not all work).
Having a little bit more information on how your setup is structured may help us help you, too.
I’m seeing OmniFocus and other task managers as the place for my single actions and repeating tasks. I don’t use OF for the 12WY setup. I do use OF to hold my goals/projects and the tasks inside.
But to track progress, I am thinking of using the Agenda app for a 12WY goal/project. I might just move one goal/Big Rock project completely out of OF and into Agenda as a test.
It sounds possible to do 12WY in OF but I’m thinking of Agenda for this instead.
Or it could be possible to have a couple of perspectives for 12WY. The first perspective is grouped by folders and is focused on a single project. It will show available or remaining tasks. I’ll call this perspective “12WY Agenda”. This shows a list of all available actions or remaining actions left in the project for me to work on.
The second perspective is the same as the first but shows Completed. I’ll call this perspective “12WY History”. This perspective shows a history of completed tasks. I can look at this perspective and review what’s been completed and any notes that I have written for completed actions.
I don’t know if I want to have a perspective showing “all actions”. I’l be irritated when I have to scroll past completed tasks just to see my next task to work on.
