Sorry, I just can’t agree with that. UX makes a big difference. I’m at the point now where entering a new task on the iPad (which is my preferred input device because of the smart keyboard always being there, making it fast to enter information) takes long enough that I don’t always use the app! Even little interface changes would help — for example, it would be really nice if when you are changing theproject for a task, the autocomplete options came up in order of recency instead of random (relevance?) matching. Similarly, why doesn’t tab switch between fields? Is there anyone who uses tabs in the text of their task? (Even if there is, that seems like it absolutely should be an environment setting)
Also, if you do have an external keyboard attached, adding tasks means constantly switching between the keyboard (because you can’t start specifying a project without typing) and the screen (to switch between task text, project, and then to select the due time.
I feel like I am probably an outlier in my use of OmniFocus — I need extensive nesting capabilities, I have a lot of parallel projects, and I rarely close a project out if there are outstanding tasks. I’m a consultant, and you can never tell when a customer will want to pick up where they left off, so deleting/archiving old tasks is rarely the right move. As a result, I have a couple dozen open projects that haven’t been touched (but which do show up when the project autocomplete is going).
