web devs more and more think browser as virtual machines rather than ui rendering engines. they keep ignoring what browsers can do natively by re-implementing wheels. web browser should stay as website rendering engines built on os native uis. today, none of these desktop browser native features are no longer assumtions in web apps, because "modern" javascript can override any of these native features, web browsers implement features like: - alt + click: open hyperlink in new tab - right click on image or link: open browser native menu - click down + slide: select text - ctrl + c: copy text - ctrl + v: paste text - uis should have browser native scrollbars as defined by operating system
