As others have stated, I’m finding it very difficult to scan long lists of projects, folders, and tasks. There’s not much visual hierarchy aside from a slight variation in font weights.
The right side checkboxes are a big part of this. In terms of design, they look great. But from a usability standpoint, they are a drag. I have to scan the right side of my task list for check boxes, look left to see what the task is, and then look right again to complete it. It’s not a big deal when the Omnifocus window is at a smaller size, but going full screen on my 15" MBP creates an ocean between the task and its circle.
