Name files YYYY-MM-DD_HH-mm-ss_<selected text>.png

At the moment I can get the extension to save the screenshot as either the date.png or the .png. I would be able to have the name YYYY-MM-DD_HH-mm-ss_.png as it would be easier to find the files in the file system this way.

In my head it would be a option to append date (in the format under the settings) to the selected text, if any.
