Suggestions for improving the organization of preferences are scattered through various issues and pull requests. Pulling it together here so we can do a few iterations.

• Introduce two new panels for "Appearance" and "Accessibility".
• Reorganize settings to more relevant placements.
• Improve copy for clarity, consistency, and remove some redundancy in text descriptions.
• Incorporate "top toolbar" as a setting (currently missing from preferences).
