Classic Tabs gives Opera 15 some of the same tab options that Opera 12 had. It lets you:
- Force all tabs to open next to the active tab
- Force all tabs to open at the end of the tab bar
- Activate the last-focused tab when closing a tab
- Activate the next/previous tab when closing a tab
- Prevent Shift+click from opening tabs in a new window
- This extension can access your tabs and browsing activity.
