Maybe you can add the following story to your product Jira board (or similar) 
As a user I would like to do the following without having to fiddle with custom drivers or external services.
“Buy a Fibaro Keyfob Remote (6 button remote pictured below) and map the buttons to be able to turn the volume of a Sonos speaker (or Sonos group) up/down by increments. Map buttons to turn the brightness of a individual light or lighting group up/down”.
The lights can then be Zigbee/Z-Wave bulbs, Hue, Lifx etc.
Nice to haves: Map buttons to tweak colors/kelvin of lights up/down by increments.
Even nicer to have: Map a button to play a specific Sonos radio/playlist, Map a button to set a specific Lifx scene (defined in the Lifx App or a lighting scene), increments for other devices, dimmer hardware and the above… okok I’m scope creeping here, maybe just stick to the original description, and make this a seperate story
I’m a developer and can accomplish this myself by diving into custom drivers (thanks to a cool community!), external services (Sharptools.io etc.) or API access etc… buuuut I think your product would be more successful if this could be done out of the box by people that don’t want (or can’t) dive into a rabbit hole of tech setup.
Only being able set devices to a specific state (and in rare cases flip a state like on/off), like to turn things on and off or set a specific volume level, color brightness setting etc. seems a bit dated by now. I can tell my Google Home to increase volume and brightness without any custom fiddling, the same I can do with my Flic buttons. Maybe SmartThings should just buy Flic, they seem to have some product owners thinking hard about covering more user stories of how to make clickable hardware more useful natively (no tech deep dive)
I do really like SmartThings and have the best wishes for success.
Btw: Nice job on the edge driver for Fibaro Keyfob Remote (single press, hold, double press, three times press etc.).
