I modified the screenshot plugin I made a couple of days ago. First, I renamed it because it's no longer the team PCT's idea, but mine.
Anyway, there's now a config file where you put in the button that will take the screenshot.
I did my best to reduce the size from 500 to 200 KB. And it now only eats 64 KB of the ram =D
While taking a screenshot, you can press circle to cancel it.
I will add the ability to take screenshots in different extensions.
And I give the source code on demand;)
Anyway, download's attached. Enjoy!
