I don't see anywhere to submit feature requests in this forum, but wanted to throw out 2 that would be great additions to Garmin Wearables. I actually ended up buying the Fitbit Sense because Garmin doesn't have these 2 features at the moment, but I'd much prefer to buy a Garmin wearable.
Garmin, please add skin temperature and ECG to your wearables (especially the Venu SQ) so I can invest more into the Garmin ecosystem.
