Chrome does it better!
- More copmact (less space among tabs).
- You can see if a tab group is collapsed or expanded (right-side arrow icon on a tab-group bar. Critical! Why in Opera there is the number instead, and we can't tell the collapse-status???
- We can clearly see which tabs are in a group - there is a vertical line on the left side. Opera has shaded color below the group - not that clear, combined with 4):
- The active tab color is hard to distinguish from the shaded colors of in-group tabs.
- The wonderful group buttons in the favourites bar, which can jump to other Chrome windows.
- The last "New tab" tab is just "+", Opera "New tab" text looks like a tab name - misclickable.
