Plugin community - stuff like pulling tasks from notes, helping with various organisational systems, etc.

Editing in a somewhat rendered markdown - it's not quite full wysiwyg, but e.g, your heading blocks are sized right, your lists are rendered as bullets until you're editing that line, etc.

Notes first UI: Stuff like the rendered view toggle, links, inline image previews are more acccessible than in vs code due to their higher relative importance.
