I use Goodnotes to create, track and make notes for my guitar practice sessions.

One of the learning methods proven effective for adult learning is “interleaving”: choosing 2 or more practice objectives and spending a short defined time alternating and/or rotating through each item in a defined time period (eg. 5 minutes per item).

The ability to attach a timer (appt watch and / or count down) to each item on my practice sheet to set the target time and record ye actual time spent on each item. Displaying the time on the notes page vs in the timer widget would be required.

I can also imagine this use case to be helpful for teaching and learning most anything.

Thank you for a terrific app and for your consideration.
