@macedotavares This seems like a nice syntax! You might get it so that Obsidian auto-generates an ID in place if you don’t supply one, and this blends well with Obsidian’s existing piped link syntax - the part after the pipe is what you actually want to display. Might even allow nested blocks! Though I’ve no idea what use you’d have for that…
And as you say, it allows people in the future to do it manually too, even outside Obsidian - one could imagine writing a parser that generates a separate file for each block, with the title being the block name and the content being the block itself. So it’s portable too. It might even be as simple as just replacing ((block id|block content)) with [[block id|block content]] to generate a note.
