Many times, more than one Screenshots need to be combine into one to make a full image. It would be great if Greenshoot had this capability. To get a round this, images are copied to the clipboard and copied to MS paint after image area is expanded in MS Paint. Then another screenshot is take of the combined images. Then images can be annotated with Greenshoot.
Fullshot (by http://www.inbit.com/downloadfullshot.html) has this capability - Would be great if Greenshot would incorporate this feature.
