Color-code the chat picker rows: a contact's dot takes that person's
chat hue (filled once talked-to, hollow before), previews light their
sender names and @mentions in-hue, and a relative age column sits
between the unread badge and the message text.
Pin a grouped list's section heading to the top row once it scrolls off
(sticky header in the frame), add PageUp/PageDown to SelectScreen, and
drop arrow wraparound in the conversation picker so it doesn't jump
across the section dividers.
