If you've a browser open whether you're at school or at work, there's a good chance there is a tab opened for social media as well.
The browser also integrates with these services to some degree - dragging and dropping an image from a webpage into the Messenger lets you share it instantly, for example.
As you may be aware, Opera is trying all sorts of interesting tricks in an attempt to differentiate itself from rival browsers, and in the past the firm has made moves such as integrating a VPN service and providing built-in ad-blocking.
These sidebar widgets are unique to Opera, and something not present in any other browser.
Opera 45's new messaging panel. If you're sustaining a conversation while browsing, you can also pin a communicator to the side of the display. With the new browser, Opera allows the messengers to reside within your browser without the need to install any extensions or apps. Since many people use more than one messenger, Opera has made it possible to switch between them using keyboard shortcuts.
Opera published the first build of its Reborn update all the way back in February this year, bringing some tweaks to the interface as well as a couple of features borrowed from its experimental Neon browser. "In this release, in addition to the new messenger experience, it brings a fresh look, new icons, colours, wallpapers and a touch of animation", Opera said in its release. As Ars Technica points out, Opera's ad-blocking tool automatically whitelists four sites: Facebook, Google, Baidu, and Yandex.
Apart from the sidebar, "Opera Reborn" also includes a redesigned UI that offers animated icons, colorful themes, and a dedicated dark mode.
