VE Sprint 22

@RafLeszczynski 
For your first proposal: the whole purpose of this change is so user does not have to click "add Map button" - because if this hash is present it means that user already click "Create a Map" in VE and having to click similar button again seems redundant.
For your second proposal: that's what it it is - user starts creation process from the VE but is taken to another page to finish it. Ultimately we might optimize / improve that user experience but not yet,
