Based on the feedback so far, I have introduced new changes to the account creation process. The notification with the list of keys that was causing some confusion has disappeared. After creating an account, a small instruction for the user appears on how to quickly start using the network using the keys that have just been obtained.

I have also added a test mode. If you see such a yellow bar at the top, it means that the creator is in test mode and the created account will not actually be created.
