Not a huge problem but it seems that in the front end (I have not tried the back end), when I create an item view and and do not specify a brick label, the brick alias is displayed as the label. If I don't specify the brick alias, the label is "from" which is the default name.
In the collection view, the behaviour is different. The brick alias is not specified as a label.
So, to not have a label for a form brick, I have to specify the label as a blank character. The work around is fine, but I think the behaviour in the collection view (to not use the alias as label) is more intuitive.
