For example, I am using a tag for NextStep.
And also, I also I use Personal, BusinessOne, BusinessTwo, Comunity tags for projects, ideas and tasks.
If I want to see NextStep tasks but only for BusinessOne I don't find a way to do it.
Since I am trying to have one reliable system to lay down all my things to do, I end un with a lot of taks, proyects and ideas.
And for what I do to focus better, I force myself during some specific time to work for BusinessOne and just BusnessOne things.
Sorry for my bad english. Hope I was clear.
Regards,
Rolando
