The new broadcast message format looks good when an image is specified, however when an image is not used it would be great if the message text could expand to make better use of the available space.
Agreed. The broadcast text used to span the full browser width, now even then there is no image it is wrapping the text in the middle third of the screen, causing the broadcast to occupy more vertical space than is necessary.
There also appears to be extra whitespace at the bottom of the broadcast message that should be trimmed.
You won't be notified about changes to this idea.
