Holyview is a tool designed to help you determine the most productive thing to work on right now. It is based on the approach suggested by Stephen Covey of classifying tasks by importance and urgency and to focus on important and non-urgent stuff.
More details here: http://en.wikipedia.org/wiki/First_Things_First_(book)
To see your takslist as a grid (like this http://en.wikipedia.org/wiki/File:MerrillCoveyMatrix.png) press the G key.
Create severals items (using "a"). Change their importance/urgence using "i"/"I" and "u"/"U". Press G to switch to grid view. Choose what to do. Do it. Save the world.
You worked on a task ? Just press + to increment its progression. The date when you incremented is recorded. This way, progression plots can be done.
As root: python setup.py install
HolyView is under gplv3+
Thanks for using my soft. Laurent Peuch
