More UI/UX distinction is needed! Just the green lock for security! The browser should indicate the level of privacy of the page. If the page use no js or any GPU compromising (css I'm looking at you), then it gets a green kind. For every privacy/security compromising feature you add the turns yellow. Once it start to ask for WebUSB, MIDI, then it should be in some kind of Native Mode. More like a UI/UX issue for the major browser makers!
