Love the addition of Vertical Tabs in Opera 140! It is a great step forward for managing multiple tabs.
To make the Collapsed Mode even more intuitive and effortless to use, here are two small UX enhancements that would make a big difference for everyday browsing:
Hover Tooltips for Collapsed Tabs: When the panel is collapsed to icons only, showing a quick tooltip with the page title upon hovering would help users instantly identify which tab is which—especially when multiple tabs from the same site (like YouTube or Google) are open.
Hover-to-Expand (Peek Mode): An optional setting where the collapsed sidebar smoothly expands over the webpage when hovered, and automatically collapses back once the cursor moves away. This gives users the best of both worlds: maximum screen space and full tab readability without extra clicks.
Adding these touches would elevate Opera's Vertical Tabs into a truly seamless experience. Thank you for the continuous innovation!
