opera released the latest version of its browser version 17. It includes security fixes and improvement fixes and also new features
1. You can keep tabs always open if you need using the Pinned Tab option. Just right click on a tab and pin it
2. Now you can choose the startup type of your opera. As of now it starts with the last session. Now you can choose options such as "Continue where I left off", "Open the Start Page", "Open a specific page or set of pages". ( still I like the startup dialogue of the older version more). to use this feature choose Settings => On startup
You can add the pages you want to open on startup (if you choose the third option) using that Set pages link.
3. You can now Search Engines of your choice and configure them.
