>My one gripe – and it's a big one – about Obsidian is that it just does not give one whit about trying to integrate with macOS.

This might get better soon.

@kepano, the developer of Minimal, is working on a new "default theme" for Obsidian. He said it "will follow many of the same design principles as Minimal, particularly in making Obsidian feel native across platforms. It will differ in that it will prioritize accessibility and affordances more than Minimal does. In addition the new default theme will make customization and theme development easier than before."
