Thanks for the detailed feedback!
For the Nest Integration, is there something specific you would want? Were you thinking that you would be able choose something like “Authorize Things” and then choose from a list of supported platforms where SmartThings might be one of the platforms and Nest is another?
For the weather feeds, I was originally thinking you could just piggy back off the existing smart home platform’s weather integration, but are you looking for a specific type of weather integration? Like rather than showing a nice visual tile with the current weather, you wanted to be able to show an X-day forecast?
Camera feeds are definitely on the list and I’ll need to put some more thought into how to best support them. I think a quick win would be to add image tile support which would add in support for many IP cameras (as many have a snapshot / JPEG interface). Do you have specific cameras that you want to integrate? Do you use Blue Iris or a similar NVR?
Sharing dashboards is on the list. If you have specific use cases in mind, I’d love to hear them.
