My reflections and suggestions on the Advanced Setup when starting a new game:
1) Intelligent Image Generation setting

This setting is in the wrong place in the logical flow according to me. It's stated to only work with "Image Generation" enabled. But that setting isn't done yet. You are referring to a setting/feature not yet introduced to the user. Sure, this is Advanced setup mode, and once you done it a couple of times you'll learn. But I suggest to place this setting after the setting for Image Generation has been done.
2) Message duration

The phrasing here, "higher means longer messages". I read this as longer, in the term of more paragraphs, a more chatty LLM. I don't think that's what you mean though? Would suggest rephrase to "higher means slower messages" (or something else, I'm not a native English speaker, there may be better phrasings...).
3) Intelligent Stim

Why is this not recommended for beginners? The help text gives no additional information to understand this. I consider myself still a beginner on Eudaimonia, why should I not use this? I would like the help text to actually help me understand.
4) Character name
Not the setup process, but I include it here anyway. I often like to address the woman in the scenario by name. But I'm rubbish at remembering names. And often she only introduce herself once in the beginning, or even that you need to remember from the setup. I like the woman's name to be shown somewhere while playing. A simple fix that would not clutter the GUI would be to change the input prompt "Answer here" to "Answer [name] here", for example "Answer Mara here", if the character name is Mara.
