ellobogrande,
I don't use project list to review my actions either. To select next actions daily I use separate list which is constantly generated on the fly by filtering with 4 criteria (context,time,energy,project group).
In other words single next actions are not separated from all other next actions even though they are also on the same list as projects/outcomes. (they could be in multiple places because I'm using a dynamic/non-hierarchical structure)
mcogilvie,
I'm not assigning "contexts" to projects but I have 3 separate project groups/categories (Personal, Work, Maintenance). I use those categories as a criteria for filtering next actions too. Context is a different and separate criteria in my system (home,errand,online and etc.). Again though, I don't look at projects when I want to see next actions and I don't filter projects. Even though I have those 3 groups/categories, I still review them all at once most of the time though, those categories just keep them sorted which I find useful.
I use project list to see all my projects/outcomes during weekly review and sometimes during a daily scan. So this is why I also keep single next actions there on the same level with projects. They have different color and icons so it's easy to distinguish them.
I can easily look at only projects without single next actions without even changing my system at all... but I have never found it useful because I would still want to see all single next actions as well as projects. Single next actions are as important as projects and sometimes take longer to complete. Note that I'm talking about single next actions and not just all next actions.
So I wonder are there any pros to checking them separately...
And what other people think about reviewing them in one list with projects. (Sure it's probably not convenient in a paper system but my system allows this easily)
