A. Explore the settings menu within DavidSW to see if there are any available themes or layout options. Often, software will have a section dedicated to appearance where you can select different styles or color schemes. If customization is limited, consider using browser extensions like 'Stylus' that allow you to apply custom CSS styles to web applications, giving you more control over the appearance.

B. If you have some coding knowledge, you can create a custom user script using a tool like 'Tampermonkey' or 'Greasemonkey'. This allows you to modify the interface by injecting your own JavaScript and CSS into the page, enabling you to change elements like fonts, colors, and layout.
