🚀 Feature: Dedicated Name field for users info

[returnedinformation]

🔖 Feature description

Having a dedicated name field inside users settings, which could be used for mail templates and similar.

🎤 Pitch

I can't separate First name from Last name when creating a mail template, the closest I can do is something like "JohnDoe has shared files with you". So having a Name field to use in mail templates would be great in which I can put whatever I like, preferably in UTF8 because we use čćžšđ here.
