This looks awesome! I currently use org-roam for a ton of stuff: personal note taking / knowledge graph, blogging, journaling, exploratory programming, etc. I'm not likely to switch away from my system, but it's hard to recommend my system to others, because Org is not very widely used, and it's not as easy to use without help from your editor as Markdown is. It seems like you could do a lot of what I use org-roam for using this instead.
