+Notable features include:
+@itemize
+@item Tab complete: most recently seen or mentioned nicks are completed first.
+  Commas are inserted between multiple nicks.
+@item Prompt: the prompt clearly shows whether input will be interpreted as a
+command or sent as a message.
+@item Split scroll: keeps the latest messages in view while scrolling.
+@item URL detection: recent URLs from a particular user or matching a
+substring can be opened or copied.
+@item Nick coloring: color generation based on usernames remains stable across
+nick changes.  Mentions of users in messages are colored.
+@item Topic diffing: the modified portion of a channel topic change is
+highlighted.
