Message History. Chat from muted blacklisted players is no longer
lost. It's saved and viewable in the new "Message history" tab: a
list of players, and clicking one opens a detail window with every
message and where it was said (whisper, party, raid, trade, …).
Automatic retention. Messages are kept for a configurable time
(default 30 days); older ones are cleaned up automatically on
login. Time span, on/off and "Clear all" live in the Chat filters
settings.
Themed scrollbars. The chunky default Blizzard scrollbar is
replaced by a slim accent-coloured thumb with clean arrow icons, in
line with the rest of the design.
Message history only archives what's actually hidden. Turn on
"Hide chat messages from blacklisted players" (Notifications) so muted
players' chat disappears from chat - and lands in history.
