i am not sure why, but if I use latest textual and rich-pixel it works and I am a hill dwarf named lord gimli !

but if I install via your requirements.txt I get this error.

TypeError: namePicker(pseudo_classes={'enabled'}) compose() method returned an invalid result; object of type 'NoneType' has no len()

line 149 in opening.py is the problem

def compose(self) -> ComposeResult:
    names = self.character_classes.get(TempNewChar)
    length = len(names)  # <- here
    yield OptionList(
        *[names[i] for i in range(length)], classes="height80", id="char_names"
    )
    yield Container(
        Button("Select Name", id="picker_button"), classes="nameCreatorButton"
    )

Hmmm ... just tried to recreate it on my end and didn't get the error. I will keep digging.

Did you get that error when you tried to "Submit" the name?

Also, I am still, by all accounts, very new to all of this. So I am not surprised in the least that there are issues lol!
