And that’s fine, but I can do that in Omnifocus if I want to.
If I’m reviewing and releasing a new document (about 50 steps currently) I can open the project for it and invoke the focus mode on that then work my way through it (or anyone of about 20 different taskpaper templates I have)
If I’m in a Shallow Work mode and ticking off Admin tasks, I can go to my Shallow Work perspective and batter through them.
If I think of something I need to remember to do, I can invoke the OF quick entry box with a keyboard shortcut and throw it in my inbox, barely breaking my stride.
I can effectively tailor what I see to my current goal… work (doing) perspectives, project views, Planning perspectives, personal (non work), or reviews (daily, weekly, monthly, quarterly, annual) quickly and easily and focus on that.
I don’t see the need to logically segregate things into different apps, there’s no cognitive load for me with it all being in the same place, and I only ever have to do something once.
And best of all, while I’m doing my various reviews, I can just add a task, change a due date or drop something right there and then and anything which is connected to it is updated to reflect the change.
YMMV, it’s why there are literally hundreds of Apps and web services out there, it’s why some people write down their daily goals/tasks on a card and stand it on their desk. Each to their own.
Don’t get me wrong, I have days when I’m in the trenches and I write stuff due soon down on a legal pad along with anything else which falls into my lap that day, and that’s how that day gets managed. But at the end of the day, I re-open Omnifocus and update it so I can plan the following day.
