"A super-quick summary of Shutter (as this isn't a review or general post) would go something like this: -
"Take a screenshot of your whole desktop, a specific window, a menu, a custom area - all with a configurable delay and optional titlebars and mouse.
"Specify the naming scheme/pattern for saved files.
"Edit files using the built in editor - add titles, icons from your installed themes, other screenshots or photos, highlight something, draw something and even order everything (can send anything drawn/added to back, front, etc)"
