I had several JARs in my module which I suspected were no longer needed. I selected them in the Project View, asked to delete and agreed to proceed with safe delete. The process took ~1.5 minute (which is OK), involved multiple searches for dependences, the progress indicator was shown multiple times. I really had no idea when the process was going to finish. It would be nice if it show single progress estimation or otherwise provide me with the cues when the process is going to complete.
