How are you gonna handle the mobile sector that isn't being handled by keychain for example.

If a contributor want to jump and make a PR to add Cordova webview i will be happy to review and go forward with it, i may create a bounty for it.
So I'd love to know what you plan to do to make the experience very intuitive.
Some of the changes we working on come from the feedback document you sent me thank you for that, here is some others things we plan to do to improve UX:
