Chat and Dice were separate panels, and a reload wiped both. v0.4.0 puts rolls in Chat and stores the session.
One stream
Messages, rolls, whispers, notices and cards now appear in one stream. The composer switches between Say and Roll. A roll shows its formula, modifier, total, highest face and lowest face.
History comes back when someone joins and loads more as they scroll. A saved layout that still refers to the old Dice panel opens without it; View and Reset layout have the current arrangement.
A player can whisper to the GM, the GM can answer privately, and two players can talk without putting it in the table stream. Hidden rolls use that same audience control. A message can be unsent for ten seconds, after which it stays in the stream.
Commands and cards
Press / for /roll, /hide, /gm, /w, /me and /table, with their arguments. /table is listed
but still sends you to Roll Tables to choose the result.
A mod can post a card with text, rows, details and buttons. A bad card is rejected before anyone sees it, and a button uses the permissions of the person who presses it. The card cannot bring its own layout or colours. Mods can also subscribe to typed events such as a roll being made or a chat message being posted.
There is no editing or deleting chat entries after the unsend window. 3D dice are still a mod feature. The mod receives the finished roll and can animate it. Dice are not built into Aether.
