Quite often I use a screendump (e.g. of Facebook/YouTube page) in Omnigraffle to add some annotations. Since the screendumps are in color, it's hard to get readers/viewers of the Omnigraffle doc to focus on the right thing.

Therefore I think it would be really nice if you could convert an image to grayscale within Omnigraffle (instead of doing this in Photoshop or other image editing software).

Do others agree?
And @omnigraffle team > would such a feature be easy to implement?
