I’m new to WordPress too and recently faced a similar challenge customizing a plugin. It reminds me of when I first learned about the kameraschutz iPhone — just like how it perfectly protects the camera without messing with the look or function, you can tweak your survey’s CSS to hide categories and style the quiz container for a cleaner look. For the popup messages, most plugins let you customize text somewhere in the settings or language files. Categorizing questions helps with averages, but you can hide category titles with CSS to keep it neat. Hope this helps!
