Let us Popout Whispers window
I can keep only 2-3 whisper tiny windows open at the same time, and if someone else whispers me, it overlays the other windows and I can't do anything. Please let us popout these small windows to another tab and session.

And it would look the same as we popout the channel chat.
Like how you can popout the stream into its own window.
