Playbook - Save images on the go

Minus 2 stars for the lack of 3 functions 1. There is no way to select and leave forever one board for images saved via the extension. The selected board constantly flies off. 2. Snapshot of an area - give the ability to change it after selecting the desired area: add sliders along the edges so that I can change the selected area. 3. Snapshot of the entire page - it used to be, but now it doesn't work, it's not clear why. EagleApp has such a function and it works great.
