Thanks for the feedback. 
We’ve been working hard and quickly adding features including Media Tiles for cameras, Weather Tiles, and more! It’s fun to look back at some of the requests to see just how many features have been implemented in such a short time.
It’s less about what I want and more about what everyone else wants. 
As you noted, I already went ahead and implemented the Weather Tiles which work based on connected platform ‘weather’ devices (for both SmartThings and Hubitat) and the Media Tiles are a great workaround for forecasts. I’ve always had the vision that I’d like to add a native weather integration with native forecast tiles, but I’ve been surprised that it hasn’t been requested, so we’ve been working on other highly requested features!
As you’ve also noted, since @Dominique’s original post we’ve added Media Tiles which handle MJPEG streams and image snapshots. Many cameras directly offer an MJPEG or image snapshot URL and if it’s not in the manual, it’s often available in an online camera database like iSpyConnect.
Thanks for sharing your experience with MotionOS here and in the other thread - it’s great to hear the integrations and solutions people are using! You’re absolutely right that there are solutions like MotionEye, Blue Iris, TinyCam and other NVR like solutions which are often a great solution for bringing your cameras into a SharpTools dashboard if they don’t directly offer an MJPEG or image snapshot URL.
