A curiosity that won’t change your life at all, but I noticed it by chance. When you have your profile verified by the client nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg, your stamp is highlighted in the color of the platform in the feed, be it pink or blue, if you prefer to change the theme; while all other users get theirs gray.
