Looks compelling, been waiting for something like this to come along. Built a couple dapps with Metamask and the popups and mnemonic phrases and browser extension installation were a serious UX issue that had no real workaround and seemingly no timeline for improvement. AFAIK, development seems to have slowed or stopped entirely on Metamask? Will try working with this and share any feedback. Nice work guys, thanks for moving the space forward
MetaMask is actually working hard on these problems, and building faster than ever, but they're big problems that aren't trivially fixed in a point release. You can expect some big announcements this summer.
