You can find a description of DWM2 by clicking here.
DWM2 does away with the page-a-day diary used in DWM, and instead uses a single list in which new tasks are marked with a small black circle or other suitable sign. Otherwise the system is the same as DWM.
An ordinary notebook can be used instead of a page-a-day diary, there is no wasted space on pages and all tasks are entered or re-entered at the end of the list instead of having two entry points.
Otherwise the advantages and disadvantages are the same as for DWM.
This is a rather faster and more convenient version of DWM.
