This is an excellent utility for laying out the blocks in the Do It Tomorrow strategy. Extremely visual with a great deal of flexibility and time management elements. Easy to rearrange items and customise. It's definitely worth having a look at a trial.
Yes I like Mind Manager, think its really good if you want to map out a specific project or something in detail.
You might be interested in MyLifeOrganized (ML0) its a Task Outliner. But whats nice is you can take your Mind Mananger maps and import them. Works on Windows and PPC.
So that tends to be the way I do things now especially if its complex. Map it out in Mind Manager then import it into MLO to action it.
Best Wishes
