I’d be even more interested in Page Shot if it had some basic drawing tools. Something like drawing a box to highlight something or drawing lines to point to something would be enough for me (or take it up a notch and include easy to use arrows). I’m sure others would ask for every feature under the sun, but I’d be happy with the basics.
I personally use offline tools for screenshots, but I’ve been told about Awesome Screenshot - I just didn’t want to install another extension and I’m happy with my offline tools. However I’d give Page Shot a chance if it had more features.
