| Not only for browsers. Once monitors got wider I moved everything left and vertical. It's also kind of a hierarchy that flows from left to right: OS -> App -> content Some content follows the same pattern (or can be configured close enough) Eg: discord servers -> channels -> discussion Eg: IntelliJ -> project files -> vertical tab for open editors -> editor Most content nowadays is mobile-first anyway, which is a nice way of saying it wastes most of the space on desktop (most webpages fit a title and subtitle OR 3 bullet points on a 24" screen) I've got around one hundred firefox tabs open currently, distributed in multiple windows on 8 workspaces and dual monitor. Horizontal tabs where always a design fail unless their number and title is fixed AND small. Made sense in physical cabinets because gravity wins and the space in a single drawer was limited. |
