Need to have "Hide if blank" button
Your behaviours allow us to hide uneditable fields, if they are blank. This is very useful! But I need to make about 10 clicks to create this behavoir. It would be useful to have this option somehwere near, for example when I right click an attribute on form, there is Editable=> True, False(hide), False(show), Expression. That would be VERY VERY NICE!
