There's already a rest day option on days that have no schedule, but it would be nice to be able to have a rest day option on days that are scheduled, yet became an impromptu rest day.. Like if work was too tiring the day before or just no energy for a workout that day, or too busy for some reason. I know it's not necessarily a great excuse to have more rest days other than the ones given in the programs, but it would be nice to track it instead of having just a "missed workout" day. Like yes, I know I missed a workout, but I could have been driving for 10 hours too. It's best to listen to your body, right?
Also, for days that have no workouts or programs scheduled, like this image, could FB add a rest day option? It's literally my rest day. I would love to be able to track it.
