I've checked out the main screen capture extensions for Chrome, and while they have annotation tools, they all require too many clicks for simple operations. Click to open the extension, click to make the capture, click to either copy or save it.

The 'screengrab' extension for firefox does it right (imho) because it offers a drop down menu with options to: copy region, copy all, copy visible, save region, save all, save visible .. this means that in one click you can tell it what to do and it will automatically copy or save what you want.

Is there a screen capture extension for chrome that can be configured similarly?
