🤖 The Mac and iPhone apps are now fully native. Chats open instantly and
scroll silky-smooth, messages are kept in a private on-device library so
your history is there the moment you tap in, and everything stays
end-to-end encrypted. Also new: pick a theme and set your display name
right in the app (⌘, on Mac, the gear on iPhone), search that finds
words inside messages on Mac, group tools (view members, add people,
rename) on Mac, and tapping a notification now drops you at the first
message you haven't read.
