Thank you for the suggestions. Regarding item #1, we completely agree that a central repository for user graphs would be a great feature. In the very near future we will be releasing support for Facebook and Dropbox graph sharing.
Regarding item #2, the next release will include this feature. Keep your eyes out this week for the "overall brightness" slider when using Artificial mode. Please note that you can currently adjust the overall brightness of Natural mode graphs.
Regarding item #3, we are constantly on the lookout for 3rd party vendors and partners to integrate with EcoSmart Live. We will add this one to our short list.
Again we appreciate the feedback.
