Can I change the loading animation on search?

Yes. In your site's CMS open Theme, then Advanced, then Loader. That is the little animation that plays while an AI search is working. Pick Default (a podcast microphone that suits any show), True Crime (a fingerprint under a scan beam), or Retro (an old TV tuning through static). Whichever you choose is drawn in your accent color automatically, so it always matches your theme.
