When you attempt to close Kate and it identifies that some of the documents have been changed by external applications, it offers to either overwrite the files, reload the files, or ignore the changes. "Reload" and "Ignore" have the same practical effect in this case, since you are closing the program anyway. Reproducible: Always Steps to Reproduce: 1. Open files with Kate 2. Modify the files with an external application 3. Attempt to close Kate Actual Results: Kate offers to overwrite the files, reload the files or ignore the changes. Expected Results: Kate should offer just to overwrite the files with the version open in it or ignore the external changes. "Reload" and "Ignore" have the same practical effect when you are closing the application, and that makes the GUI confusing.
