It doesn't feel like a part of the tool since it appears outside of the initial box.

I understand you put it outside of the box because it loads more boxes below the entire tool, and now that I know about it it makes "sense." But my initial impression is to ignore anything outside of that box.

I think your best bet for brand spanking new users is to place it as a button inside the box in between the "generate rift" and "play" button to make it stand out.

You're literally hiding 80% of this tool from initial users. I clicked "generate" a few times then bounced at first.
