A body like Taskpaper with a brain like Omnifocus.

Is there a good-looking task manager that lets me sort by date added, but also has recurring tasks and iOS sync? I use Omnifocus, because I need the recurring tasks and due dates. But I tried out the Final Version system and Taskpaper, and I loved it. Forcing myself to start on the oldest task cleared out a lot of old, sticky to-dos, and the simplicity of adding and crossing out tasks was so satisfying.

Unfortunately, I lost track of due dates and recurring tasks, and the syncing on iOS kept doubling or erasing my lists, so I'm back to Omnifocus.

I would love a task manager that is:

- Simple and fun to look at (like Taskpaper or TeauxDeaux)
- Lets you sort by date added/created, or that just adds tasks from top to bottom and keeps them in this order
- Syncs seamlessly
- Has a flag or tagging system so I can just look at the top task and other two I have selected

Does such an app exist? Thanks in advance.
