Roadmap

• Enable dataset values focus to copy values easily
• Improve rendering UX -> Multithread -> Rendering spinner
• Fix issue related to segmentation errors (last segment fetched too many)
• Fix issue related to many attributes then ending up taking all space. Maybe constrain to 25% and then add browse mode thing to navigate attributes when many.
• Add matrix support for compounds
• Add preview support for compounds (select fields to preview)
