I would like to suggest implementing a full dark theme across SQL Developer. While there is already a dark theme option for the code editing interface, other interface elements such as menus, toolbars, results windows, and side panels still use the light theme, which can cause visual discomfort, especially for those who spend long hours working with the tool.
A unified dark theme across the entire development environment can improve the user experience by providing a more pleasant visual experience and reducing eye strain, especially in low-light environments. Additionally, a full dark theme has been a popular request among developers and has been adopted by many modern development tools.
