@Mlipka I personally like how Arc did vertical tabs as a kind of bookmarks.

I have a lot of nested folders in my vertical tabs to easily switch between different roles I play (business owner, cto, accountant, developer, gamer, researcher, etc.)

With horizontal tabs I just get a big pile of favicons and I can't tell which is which. With vertical tabs the tab titles are still visible and I can still scroll through them legibly.

I would love to have vertical tabs in all versions of Opera, not just Air.
