Request: please add new activities

You have a few options. Assuming you have a relatively new device that can use Connect IQ, 

Badminton in Connect IQ Apps

Not sure of your device model, but you should be able to add any sport activity you want. Check out your user manual and search for "Creating a Custom Activity." Here it is for the Fenix 6.

Wingsuit and Hang Gliding are there, but not Skateboarding (and its variations like longboarding, commuting, downhill, skatepark)
Inline skating is there, but not rollerskating (quads are making a comeback in some areas)

There are around 8000 of sports that are not listed on the watch, and each day new sports or activities emerge. That's why you can (on most Garmin watches) create a custom activity. Or just use inline skating for tracking your rollerskating and skateborading activities - it will offer you all you need for that purpose.

If this is something that you feel should be part of Garmin Connect, rather than creating a custom activity on your device, then best to submit using the Share Ideas form.

Thanks for the advice and the link to share ideas.  I just made an entry on that page.

+1 after two years there are no badminton still

If adding a custom activity or using a Connect IQ app is not an option, then you can request it using the form - Share Ideas

Correct. None of the band style wearables have Connect IQ capability.
