Something like the old Opera: - Extensive customizability of the interface - Proper tab management (tiling, cascade, positioning) and tab stacking - Mouse gestures - Content blocker baked in - RSS reader included - Better cookie control - Per-site privacy mode - low CPU/memory usage - no "one tab per process" - I want 10s of tabs open without wasting few GBs of memory - fast JS - advanced search from address bar - custom search engines with search suggestions - customizable Speed Dial baked in - no extensions needed. - Dragonfly instead of DevTools - detailed page loading info, not just "Loading example.com..." I'm hoping to get at least some of these things out of either Vivaldi or Otter Browser when they're mature enough...
