Change register and login title above the form

There is no option to change this title

Yes there is. This is defined in the file mb-user-profile > src > DefaultFields.php at line 25:
'title' => 'register',
Why this is hardcoded is beyond me.

It seems like every post I make ends the same way. Here to, this is true:

@rilwis
I am more than happy to contribute a pull request to either a) Allow the title to be translated:
'title' => __( 'Register', 'mb-user-profile' ),
or allow the title to be filtered / set to blank within the shortcode attributes.

What's the best way to upvote this? This problem caused me to abandon using Meta Box for user registration. I don't want to have to maintain alternative code.
