If no timer is running I'm not producing results.
Ideally I'd want to track my "no timer running" time.
Maybe a quick fix would be to add next to the running timer number at the top an indication of what timer is running, and when no timer is running have it say that in bold letters and track the time that has accumulated today.
This would really help focus on using time productively..
How often would you use this request?
Multiple times a day.
