So it's just the front-end, relying on you to manually write all the HTML. I'd love some software to make generating these (or similar) annotated documents easily. Any ideas?
Also, I'm sure you didn't mean to trivialize the project, but it's more than "just a front end". The design is what's really great about it.
Well, all it does is generate her identical format from a spec. Like @bradgessler said a gui to coerce annotations to that format from highlighting would be awesome
Obsidian gets this right. Most software these days doesn't which is a shame.
