Just a newbe, but this is ridiculous. scrolling around a blank screen hoping a menu pops up - oh and adding another section that maybe you can find and drag what you want from that section to another, then deleting the section you didn't need in the first place. Videos talk about the entry points that are basically invisible, or teardrops that are or are not in the newer version.
Seriously just add a button that says BLOCKS, and figure it out from there.
Sort of like learning a new video game with all the hidden functionality and no instructions.
