When I have auto save a screen capture on it comes up with a dialog box asking to save the file.  Why can it just automatically save it?  why does it have to ask?  I already specify in the settings what the filename format should be, so why is it asking?

Also it should be smarter, if my format is image0001.jpg, then if that exists already it should automatically call is image0002.jpg.  right now it doesn't.  version 2.1.5.
