Naive users tend to just hit Enter and let everything be saved to a default location, which is fine. (In OS X, the default collapsed state of the Save panel supports that.) Users who are savvy with the filesystem know how to navigate to a different directory if they want, or at least look at where the file's going to be saved by default.</div><div><br></div><div>It also doesn't look like the type of security-nag dialog that people instinctively OK without reading.</div><div><br></div><div>—Jens</div></body></html>
