The suggestion is pretty straight forward, add the ability to space with your name. This'll make a prettier game, name-wise and enable those who use a first and last name to have a space between the two.

An example would be YakuzaMaster, turning into Yazuka Master.
Or perhaps, MariaNamikaze turning into Maria Namikaze.

It just seems like a basic feature to have the ability to present your alias however you wish when it comes to having two parts to your name. I know its a minor suggestion, most who read this might think it's irrelevant and that it shouldn't be a suggestion - but... I personally think it would be a neat addition to have pretty names.
