I use the 'save current frame' quite a bit in my projects. It's nice way to capture screenshots for thumbnails and newsletters etc.

I'm wondering whether we could have this same function available in the media library?

Sometimes when I want to snip an image from video footage, I can find it in the media library. However, often I haven't used it in videos or don't know in which video it was. Therefore being able to take 'screenshot' in the media library would be very helpful.
