Not sure if you want to change his implementation but maybe we should split up the blocks into individual ones instead of the "sub-blocks" that he originally used?
Just an idea, tell me what you think

It would probably make implementing new blocks and reading the code easier. I think the sub-blocks system was used when they had block IDs, so you only needed to find one open ID.

Was it an accident that you re-opened this? I've been working on it for a while, if you still want to do it

It's very easy to do but I don't think it's a good idea. Easier to maintain when you have code in one place.

I think it would be much easier to look at the code. It might be easier to maintain, if you can break one of the blocks and not all of them.

Keeping it all subblock stuff, for better or for worse.
