In my line of work, apart from taking notes on a daily basis, I also need to constantly keep track of status, progress and results, which are not always presented in a text form. The solution is to take screenshots to preserve the state, which at the moment I would have the link the image file into CN.

While I'm not sure what's the best way to manage the image files i.e. in CN data/image folder or imbedded into the .db file (but I wouldn't want to compromise on the tiny of CN database), or perhaps some other, better way? (also need to think about synchronization with Simplenote which does not support images). That being said, this feature would be an instant killer.

How about a hot-key to take a snapshot and automatically compress the image to a minimum size? Think about it!
