Make new wallet in testnet (Lot of debug messages)-> Address Action -> Enhanced Feed Broadcast (Close Message about money. Is temporally without money)->You see current form. Now it does nothing. I'll have to add the logic of which you spoke and change the design and styles of text fields and categories.
