When you add a friend you can write a short note. Only the person you asked sees it, and it is deleted once they answer. You can hide notes from Privacy. A friend request, and its acceptance, now reach you as a notification with Accept and Decline, which you can turn off under Friends.
A call’s ring names who is already there, a big room starts you muted, and the Mute and Deafen you chose stay with your account across reloads and account switches. A stream can be pinched to zoom on a phone, and a long thread has Jump to present.
If you are removed from a community, its tile leaves your list straight away and you are told. A followed forum post offers Close and Lock in the sidebar where you may use them, a gallery picture’s menu has the same moderator actions as a forum card, and a post page opens its menu on right-click.
