A common feature in Linux window managers is the ability to have multiple “workspaces” or “virtual desktops” or whatever you want to call them. From the i3 docs: Workspaces are an easy way to group a set of windows. By default, you are on the first workspace, as the bar on the bottom left indicates. To switch to another workspace, press $mod+num where num is the number of the workspace you want to use. If the workspace does not exist yet, it will be created.
