• New: the block/mute button now also appears on profile headers (next to Follow) and on user lists (followers, following, people search).
• Blocked accounts' posts disappear from the page instantly — no reload needed. On profiles, X's own UI reflects the block immediately.
• Settings apply live: switching block/mute in the popup updates every open X tab on the spot.
• Simpler options: section toggles consolidated into 5 clear surfaces (timeline & communities, replies & mentions, profiles, user lists, search & explore).
