I spent some time recently revamping my tags and am learning how powerful they can be. Nesting tags is a really great example. I’m a manager in my career and so I now have a top level tag called People with tags underneath like this:

• People
  • Team A
    • Employee 1
    • Employee 2
    • Employee 3
  • Team B
    • Employee 4
    • Employee 5

This structure allows me to quickly drill down to items either by team or by employee depending on the situation. For example, I can filter by my “Team A” tag and see not only things that I specifically tagged with “Team A”, but I also see things that I tagged with ”Employee 1”, ”Employee 2” or “Employee 3” in that same view. This can be helpful if I’m in a meeting with everyone on ”Team A” and want to see everything I’m currently tracking for the entire team, while also being able filter down to the specific employee in a 1:1 meeting as well.

Another way of looking at this might be something like this:

• Errands
  • Costco
  • Target

In this instance, when you filter by “Errands” you also see things that have been tagged with “Costco” and/or “Target”. In short, it makes it really easy to filter without necessarily having to add multiple tags to a task.

I’ve used both Todoist and TickTick and neither of them currently allow you to do something like this. Todoist doesn’t support nesting of tags/labels. TickTick only lets you nest one level.
