* Hints or error messages appear in the top banner. This is not obvious. If you moved the messages closer to where I am looking, that would be more helpful. You could simply move the message to the middle of the screen or in some cases pop-up a tooltip next to the component that has the error or hint. It also does not help that the news banner is a similar color to the error message box.
* It is not clear what the blue, green, etc arrows and squares mean. I tried hovering to see if a tooltip appeared with a short description but none did. I think the blue arrows are for networking, but not totally sure.
* I have no clue how to connect any of my instances to the public internet gateway or even if I can. I tried connecting an instance directly and I also tried using an LB.
I don't know if any of my UI suggestions are correct so please take them with a grain of salt. Just trying to give possible ideas that may help. Like I said, I like the concept and I think it has potential. But I think a lot more work is necessary to make it easy to use.
