I'm going to try to describe *how* I use 2do to track all of this.
First, I set up my "calendar tabs". These sort the tasks on my list into various separate screens, each with its own colored label.
When I choose a view that includes all the calendars together, each task item shows a colored bubble identifying the calendar to which it is assigned. Therefore I defined my calendar tabs as people in my household, so that I could easily see which person needed to do which task.
I also began assigning tasks to categories. These don't display unless you drill down to the details of a task, but I can search for a category and then define a custom calendar tab that isn't really a separate calendar but that displays the results of that search. So I can make a tab that shows all the "school" items anytime I click on it, for instance.
A couple of types of tasks needed special handling. School tasks and chores didn't work as well when they were defined just as regular tasks--they tended to overwhelm the to-do list so that other tasks were obscured.
Chores I set up as a special type of list item called a checklist. The individual items on the checklist are not set up to repeat, but the checklist itself is set to repeat weekly. So during the week we mark off the items as they are done, and at the end of the week we mark off the whole checklist, and it regenerates itself with all its items just as it was before, but with a new due date.
School I set up as a special type of list item called a project. This way I could assign a time to each item. However, this type of list item causes each to do on it to display individually on the calendar, and I wanted them all to be contained inside the project like the checklist items were. I only wanted to see the individual items when I drilled down. So after I defined all the tasks and assigned them their times, I changed the type of list item for the "school" project from project to checklist. The times remained (but I can't change them without changing back to project) but the tasks no longer show up unless I drill down inside of school.
