It would be great if the cycling dynamics data generated from the vector pedals (and soon others after the ANT+ TWG decides what to do with Garmin opening up the spec https://www.dcrainmaker.com/2017/10/garmin-opens-up-cycling-dynamics-to-other-companies.html) be displayed on screen.
If that information can be incorporated into workout mode then specific workouts can be generated to help improve form and efficency.
This would give feature parity with TrainerRoad (https://www.dcrainmaker.com/2017/09/trainerroad-adds-garmin-cycling-dynamics-support-plus-upload-to-garmin-connect.html) which recently got this feature.
