Search is basically unusable for anything older than a few days - it's really slow to display the conversation that's clicked, then goes back to latest message after seconds for old messages around 3 weeks old and older, and goes back to latest message after minutes for messages a week old. Search performance goes downhill fast the older the message.
There are plenty of features, but the key needs are chat and searching of chat.
