Excuse me from asking, but why would anyone want to use this? You've said that the wallet uses public APIs and so, your IP can be tracked, that the users should be extremely cautious etc. You've literally called it the most dangerous wallet, and it's true. There are many things you should be aware of such as your browser extensions, programs that have access to your browser etc.
Sure, it might was a good exercise to code it, but to serve it as a "fast & anonymous wallet"? I think it's just bad. Benignly.
First of all, this is a Project Development board, not a Service Announcement. So I'm not asking anyone to use it -- I'm sharing an open source project.
Second, you can't come up with a reason why someone would want a single-page open source instantaneous web wallet without setup or registration that they could run from their own machine? Hmm... that doesn't seem sincere but okay.
As someone who develops browser extensions I can say that I'm aware of their localStorage access capabilities and their risks. I can also say almost all the same things about desktop wallets. Seems rather naïve to be coming from someone with "BlackHat" in their name but your IP will be also leaked using a desktop wallet to the wallet server, and malware may steal your keys stored on your PC.
