Prettiness.
Is there any way end the auto-scroll? A bit slow on my old Mac.

I like this style a lot. There are more color variants than i'll ever use (seriously, 90!?), but it's a simple style and I keep coming back to it.

Note: There's a bug with the new header and message history, i think, with 1.3: the last message sent in the history is too low to be visible.

The colors aren't the same as here, are they?

I would have to agree with you. It looks really similar.
