We all get a little over-ambitious with tabs sometimes, opening so many that we lose track of what we’re doing. Then the problems start. The text on tabs is hidden, so we can’t find the tab we’re looking for. Multiple loading tabs slow down the browser. Tabs are forgotten, never to be seen again, and what we were working on to begin with gets lost among the cacophony of open tabs.
This is why Opera has created workspaces, which allows users to organize tabs and keep them in distinct groups. You can create a separate tab group for work (aptly named), a research project, shopping, trip planning - whatever is relevant to you - minimizing the number of tabs in your window and compartmentalizing your projects. Use an existing group or create a new group of workspace tabs as needed.
Workspaces exist as customizable icons on the top of your sidebar, so you can switch between them quickly and easily. This smooth transition not only puts an end to awkward managing, searching through, and reordering tabs, but also helps you focus on what you’re doing.

To manage your workspaces, open the Sidebar setup panel from the three-dot menu at the bottom of your sidebar, where the feature is enabled by default. From there, you can easily create, customize, hide, or delete tab groups, as well as manage other useful tools and features in your Opera browser.

More options for workspaces are in the tab menu, like moving tabs (or a set of tabs) to another workspace. The tab menu is made available by right-clicking on an open tab. The tab options, like reloading all tabs or highlighting duplicate tabs, work within your active window's tab group only. Equally, the visual tab-cycler (Ctrl+Tab) shows you the tabs in your current workspace, so you can continue to focus on the task at hand. Like all of Opera’s features, the Workspaces feature is a quality-of-life browser tool that greatly improves your work, play, and daily browsing.
