Quick Q: while testing this I'm finding spin isn't animating nor printing the command's output. Maybe user error? Getting this regardless of whether I use a --show-x flag or not. It just prints the first render of the spinner

I think it needs to be

gum spin --show-stdout --title "Running command..." -- sleep 10 && echo hello

for me the command you provided exits 1 🤔

Ah I get it now! Thank you :D Looks great
