Like Windows 10 virtual desktops feature, Ubuntu also comes with its virtual desktops called Workspaces. This feature allows you to group apps conveniently to stay organized. You can create multiple workspaces, which act like virtual desktops. Workspaces can be used to organize your work which reduces clutter and make your desktop easier to navigate. If you keep a lot of apps open at once and you want to separate them by tasks, using a virtual desktop or workspaces may be useful. For example, you could have all your communication windows, such as e-mail and your chat program, on one workspace, and the work you are doing on a different workspace To use workspaces, click Activities above the vertical bar (dock), then move your move to the right of your screen to show the workspaces in used plus one empty one. To add a workspace, drag and drop a window from an existing workspace onto the empty workspace in the workspace selector. This workspace now contains the app you have dropped, and a new empty workspace will appear below it. To remove a workspace, simply close all its windows or move them to other workspaces. there is always at least one workspace. This is the workspace selector. You can also move apps from one workspace to another by simply dragging and dropping the apps onto the other workspace. This workspace now contains the apps you have dropped, and a new empty workspace appears at the bottom of the workspace selector. This is how one uses workspaces to keep applications and files organized on Ubuntu 18.04 desktop.  Hope this helps you get your desktop organized. Enjoy! You may also like the post below:
