AutoStack

When you open a new tab from within a tab stack, AutoStack will place it inside the stack rather than next to it. This extension requires Opera 12.00.

By default, AutoStack will not stack Opera-specific pages such as Speed Dial, but due to a bug in Opera, AutoStack can only determine what is an Opera-specific page by checking its title. If your browser is not in English, you will have to go to AutoStack's preferences page and change the list of tabs to exclude.

Known Issues:
- Exclusions only work for internal tabs, since regular tabs' titles are "Blank Page" until the page has partially loaded. Eventually, I want the exclusions list to work on URLs instead of titles, but tab URLs are always undefined at tab creation time. Hopefully Opera will fix this.
