Sometimes (like, often) 'select an area' doesn't work as expected for a website or fullscreen grab. I also want to crop a specific part out of an application screenshot.

I bought this deal but it's killing my groove I can't crop basic screenshot images!

Otherwise I see a lot of uses for this, but not if I have to open another image editor or screen grab tool anyway.

Thank you!

P.S. Being able to crop ("zoom") or change the aspect ratio for screencasts/videos to commonly used sizes would be a great bonus.
