Every task in your Planning Cycle has its own notepad, so you can jot notes, ideas and progress against that exact task. Open a task and start typing in the notes area.
You can click the three dots (...) to open all your notes whenever you want to check or edit retrospectively.
What to use it for
It's handy for parking your thinking on a task, catching an idea before it disappears, or noting where you got to so future-you can pick it straight back up. No more needing to scan through a messy notes app on your phone.
