It is absolutely part for the GTD system. Next Actions, according to the book, should be engaged using the following criteria: 1. Context 2.Time Needed 3. Energy 4. Priority.
IQTell (which has announced is end) had the ability to sort by all 4 of these. I believe it is essential, when looking at a list of Next Actions, to NOT have to think about how long each one will take when selecting (which may take up most of a 5-10 minute period that could have been productive).
The whole point of GTD is to think ONCE about an action.
