Viewing the Running Processes
The main Notebook page, where you choose which notebooks to open, actually has three tabs. You normally interact with the Files tab. The Clusters tab is no longer used, so you don't need to worry about it. However, the Running tab, shown in Figure 5-8, does contain some useful information in the form of terminals and open notebooks.
