NEWBIE Question or feature Request

Hi all,
I am a new client of Meta Box AIO. I don't have much experience with WordPress plugin development, but I hope I can learn to make nice plugins for my clients.

It was easy to make my first Custom Post Type and Custom fields.

I didn't see it in Meta Box but it would be really nice if I can make "add_help_tab" with my custom post types.

And is it possible with Meta Box to create links with search queries for post types?

I will give an example code below. It would be very nice if it would be possible without custom PHP code.
