The best place to put your personal to-do lists would be in a Private Stream under Other Streams. You can create different streams to have a place for your daily to-dos, personal reflection, or even your personal goals. Here are some more ideas about how to use these streams.
Notes in Private Streams work just like any other note in Fellow. You can add any action items, notes, etc. You can create a new note each day to have 1 ongoing stream of your personal todos.
And you can set it up so that any incomplete action items/talking points are carried forward. (To set this up click on More Actions in the top right corner of the page --> Stream Settings. Learn more here)
