I use Strava as a personal workout journal. As such, I frequently like to make notes or have comments (injuries, illness, reasons for not working out, equipment issues, etc.) on days that I don't work out. To my knowledge, the only way to do this is manually add a workout, pick a sport, put in 1 second for duration, then make my comments. It would be helpful to have a function where an athlete could just make notes without picking a sport, adding time, or having it count as an activity.
Otherwise, love all the positive changes you have been making! Keep up the good work!!
