I move blocks around. Some blocks I can attach to the bottom of "run this program" block and they clearly run. But I was unable to add any more blocks that did anything.
The screen is two dimensional so I was expecting to be able to put processing blocks anywhere. Sure I can but they do nothing.
What's missing (for me at least) is an explanation of the user interface.

The blocks with a square side are commands you can attach to each other to make a program. The round blocks go in the round slots on other blocks.

You can click on them to run them without them being connected to a "run this" block. Whatever has a yellow outline is running.
I suppose there's a reason node editors use a block and line interface mainly.
I'd actually prefer a tree-structured approach, where you could turn a subgraph into a single block, allowing you to structure appropriately.
