Some operations require a bit of processing time to finish. To keep you notified on running tasks you can click the small clock icon near the top right corner.
This is your 'Process queue' (1). In the Process queue tab, you can check to see the status of your operations and in what order they are in. Once an operation is completed, you can see the summary in the 'Recent Processes' tab (2) of the Process Queue, as well as who carried them out.
