Opera has released the newest version of its browser for Windows and Mac called Opera 15. The new version is a Chromium based one and uses the same engine as Google did, the Blink.
The new browser gives its a feel of Chromium and This shift makes Opera look and behave a lot like the Chromium browser will be puzzled for a moment as to whether you are Opera or Google's Chrome. The address bar can be used as a search box similar to Chrome’s omnibox. The Google search box in the older Opera have been removed as the address bar serves that purpose.
Opera has refreshed the Speed Dial page which now lets you organise shortcuts to web pages in folders and filter your shortcuts by folder. This is particularly useful if you have lots of shortcuts.
Opera has imported the "Discover" tab from the companies Android browser version to the PC and Mac. If you use Opera App for Android you will know the "Discover" tab which shows content from a variety of sources based on your location and some categories such as news, food and entertainment. You can add or remove or customise the categories from a list as per your choice.
Opera also has a all new "Stash" feature that lets you stick complete websites to a tab by clicking a heart icon in the address bar. Now this a real positive thing from the Opera guys. Many a times we visit some pages which are not relevant to our search at that point of time but may be useful later. With this feature you can “stash” previews of multiple web pages for later reference and then view all your stashed pages together at your own convenience. The Stash tab lets you zoom in and out of the previews, but you can’t rearrange them and clicking on a preview will lead you to the page.
Though the company has said this is a stable version, but expect many updates to follow this version. You can check out Opera 15 by downloading it here.
