A sticker in a message opens its details: a larger picture, its name and description, whether it comes from this community or a Kemble pack, a star for Favourites and Show pack. The sticker pickers now open with Favourites and Frequently used, kept with your account, and typing a word in the message box can suggest a matching sticker (Settings › Chat › Suggest stickers while typing). Edit friend nickname, in a friend’s menu, names them in your friends list, your conversations and their card; only you ever see it.
The pinned bar has a Pause rotation button and names a sticker, GIF or poll pin as the Pinned messages panel does. If a tab that was recording a Link closes, the person who started it can stop and keep the recording from any other tab. The GIF grid keeps going after a page fails, with Try again, and the channel details’ Media grid blurs or hides pictures marked sensitive by your setting.
