A UI is a common request, something I’ve been considering investing effort into. I don’t think we’ll ever have one in the core package, but probably as a separate package/plugin (even a third party one); we’ve been thinking more about the events and APIs such a system would need and making these available, and adding a plugin system to enable tighter integration.
Could you expand on what’s missing in the documentation? That’s been a focus recently (as you may have noticed with the new expanded docusaurus site linked previously rather than just a README), but documentation can always be improved.
