Workout mode in Companion App is very nice but I miss a few things.
Incline adjustment for smart trainers that does not have ERG mode.
The blue Icon bar that is at the bottom of the Map page it will be helpful on the workout page as well.
Multi ride-on from the workout screen. I like giving ride-on’s while riding and the button on the map make it so easy, having that on the workout screen will be helpful.
