automatic sequential numbering is needed

Unless I’m doing something wrong, whenever I click SAVE (to save the screenshot to a pre-defined folder) it uses the default Untitled.jpg or whatever filename—so I need to manually rename the file or it will overwrite the previous screenshot). Mac OS X’s default screenshot capability (automatically saving successive screenshots to the desktop and sequentially numbering them) is better than DreamShot, in this regard.
