Add "Do not show this message again" for "Save" warning message
Hi. When we use "Save" option, there will be a warning message will emerge saying:
"A file called XXXXX.pdf already exist. Do you want to overwrite it?".
This is okay, but it is annoying to see this message every time user click "Save" option. So it will be useful to add a check box within the window of this message for "Do not show this message again."
