Big Sur Messages app Window Width

I just installed the public beta and noticed that the Messages app window is much wider than in Catalina.

Is there a way to force the Messages app window to be less wide?

I hope you have that on a separate bootable volume ?

Nope. It’s my primary work machine. :slight_smile:
