Awesome work! Just tried out the demo, it's awesome that it's compatible with the new Steemconnect chrome extension, Steem Keychain and if none of them is installed redirects to the regular Steemconnect website. However, the demo didn't return a steem:// URI that would be opened in the desktop app, I guess it's not possible to detect if a desktop app is installed, is it? I really like the idea of having a steem:// URI and a desktop app though, that's what I love about Scatter.
If the release is one month away, I guess it would probably best to launch the beta with v2 and only deploy v3 in a month, or is v3 safe to be used in production already?
