But I can't go to command line and tell it "delete all of the files from the project X I do not want anymore" or "find me the change in this file in the history that caused bug Y". Sometimes it is better to mass delete files with a find, grep and rm, sometimes an auto-filtered search and cmd+a cmd+delete is better.
