I have added a NiceSavePNG function which allows one to save screen shots of individual windows from within your web application.

Several popular libraries don't work with EWB, though they do with most other pages.  But I found one which does.

It works with Chrome and Firefox.  Not as well with Safari.... clips the bottom a bit.  IE? Not a chance.

I tried using the Javascript PNG to PDF converter, but the perfect PNG file was mangled to be illegible, so I save as PNG for now.

it offers a preview, and the user can select the filename.
