Set a character limit in the Text Field Element (Widget)

Hi~
I don't know if this was already suggested but it would be great if it was possible to define a character limit for the text field element (Widget). Personnaly I want to create a simple character customisation at the start of my game and I also want the player to be able to enter a name but... as of right now the player can write a whole sentence in the text field element!
I think it would be great to have the option to choose a character limit in the text field property.
Another small suggestion, maybe adding the option for the text field element to only contains numbers? So with the character limit and the "only number thing", it would be possible to offer to the player an easy way to enter a code.

Thanks!
