For what should we like hide a license key? Please give me some arguments to make a decision.

@artemiv4nov

1. For privacy: to prevent the key from being accidentally seen and then used by a third person.
2. For better appearance: the key can be up to 25 characters, the license screen will look better if the key will fit one line.
