I can't find a block. Where is it? (Spoiler: Switch to advanced mode)

[pikurasa]

Have you read an issue that describes the behavior of some block, and you're like "I can't find this block anywhere, and I've checked all the palettes -- what are these people talking about?"

Well, that's a good question.

It's not obvious, we admit, but there is an "advanced mode" that unlocks more blocks.

This is how you get to advanced mode:

1. Click the hamburger menu in the top-right of the screen
2. Click on the start
3. Click on the hyperlink that appears at center that tells you to refresh your browser to start again in advanced mode
4. You should now be in advanced mode
