Click through the slideshow to see what each block pack does. Then, drag the packs you need into the backpack. PS. For the Dicts pack, you should create a global list named "dictionary data" if you want global dictionaries to work correctly.
I don't really care if you give credit or not. It'd be nice if you did, but only so that I know how popular my block packs are. I deleted the "keyboard" pack because it only contained a single block, and its only use was to emulate the "key pressed" block, which already accepts reporters.
