Feature Request

First of all, I just want to say how much I love this plugin. I tried them all and this is by far the best. Thank you!

What I would really love to see added (if possible), is the ability to disable the hot keys for taking screenshots on both Mac and Windows. EG: Shift + Command + 3, Shift + Command + 4, Shift + Command + 5.

Also, I noticed the image downloader extensions still work . From my understanding, that is a bit more difficult to prevent because they download images the same way the search engines crawl the site so if you disable that, you are blocking the search engines as well. Is this correct?
