Hide license key

I'd rather have my license key hidden on the registration dialog. I don't think it serves any purpose as it is, and it's too easy to steal it. The Buy online button is also not needed after registration (maybe replace it with a re-license button?).

I didn't think this thoroughly, just an opinion from the top of my head.

Good idea, thanks! I will work on this.

Is there any other place where I can hide my product key where it is not possible to be found? And can you further explain on what other way could someone extract a product key from my computer? I'm sorry for asking but I'm really not that techie girl.Thanks in advance
