Brief Summary
SuperFocus is basically AF1 with a second column added for unfinished and urgent tasks.
Advantages
As in AF4-3T the emphasis is on finishing tasks. However it is more flexible and doesn’t slow down to the same extent when a number of longer tasks are being processed at the same time. It also allows urgent tasks to be done quickly.
Disadvantages
It can become rather directionless with a lack of proper balance between the two columns on the page. These disadvantage will be overcome by the forthcoming v. 3.
Conclusion
At the moment SuperFocus suffers from some disadvantages, but when the new v. 3 is released in the near future it will be the perfect time management system.
