Killer feature for me was the ability to take a sceenshot and leave it on screen while continuing to take new screen shots. Makes is really easy to "stitch" together a story.

Taking notes is straightforward if the source is text. You simply select the snippet of text and copy them. But it’s a different story if the source is an image. Perhaps you want to write down quotes from a movie, compare the mockup with the prototype, or follow the instruction in a tutorial. You need these visual notes to be pinned on top of the desktop all the time.
Snappy is designed with that purpose in mind. It captures a screen area, pins it above all of other windows, and stays there until you close it. The pinned snap appears on all the desktop so you can snap an area in one desktop and bring it to another desktop.
