Since you can hide commutes from training logs, you should be able to hide from Stats
It's annoying that you're able to hide commutes from your training logs, but you can't exclude commutes from your Stats.
For example I only care about Stats for mountain biking - but I commute to work on a single speed pretty often. So I don't want my mileage, elevation, etc getting mixed together from the 2 types of riding.
You should be able to separate My Stats by commute/non-commute and by bicycle name if you've added your bikes to Strava.
