Thank you for the feedback it is much appreciated, I have addressed the content issues in the documentation. I also have made a request to see if we can enable Gravatar (I am a big Gravatar fan as well) and asked if the company field can be made not required.
Our device simulator is built with the Google Webkit tools with Ripple as our bridge layer, you can see a list of projects we use in one way or another in the Beta EULA
. We do not use Weinre currently but you never know what the future holds ;). For building for debug we don't differentiate builds but depending on the certs you use you may not be able to deploy to publicly but i don't think that is what you are asking.
Thank you again for the feedback and please keep it coming.
