The Vertical tabs need to re-design to optimize looking and spaces. Here is some ideas:
- Focus on the tab names, other details need smaller - The scroll bar need smaller or only show when the mouse is scrolling - The color of group vertical line to bright and big - The active tabs hover background is a bug. There are 2 layers appear when I move my scroll mouse around
And by the way, vertical tabs is great way for me to surfing the web. The browser is great performance than Chrome.
