A common aspect of my apps seems to be setting a pace, and the problem being having to manually create that in settings from minutes and a seconds input box. It's not a great customer experience and would really benefit from being able to change it on your device, even mid activity.
If garmin created a 'pace' type that could be used in settings it would allow garmin to create a great CX that all the connect IQ developers using pace, could benefit from.
On top of that there's the opporutnity to get some really easy functions out of a pace type ie pace.getInMetresPerSecond() or similar utility functions.
It would also mean there's a possibility for garmin to create on-device settings changes to allow changes to pace setting for workout apps
