Taxonomy term reference settings form: "Vocabularies" and "Create referenced entities..." look related

Not a great patch, but often simple things are better...

Some specific CSS border would be bad in form.css file.
We can put the auto_create field in a fieldset, hum.
I have no idea

I removed the addition of a custom element, and used some CSS, using a border-top as separator.
What do you think ?

Rerolled

I guess we can't separate the 2 checkboxes that belong to the same list.
This is why I tried with CSS.

I agree with @LewisNyman, let's just move the auto-create checkbox above the bundle selection form element.

It is easier now (The code has changed a lot!).
This is a totally new patch, without interdiff then.

This gives :

-    $form['target_bundles']['#title'] = $this->t('Vocabularies');
+    $form['target_bundles']['#title'] = $this->t('Available Vocabularies');

Can we change user facing strings now? Aren't we in string freeze?

Hum, you are right ! Depend if we keep this in 8.0.x or for 8.1.x ?
I guess this string improvement is not so important. I removed it.

As a UI change, this is a minor version target.

Edit: And as such, we can include string changes if we agree they are part of the best fix. Reference: https://www.drupal.org/core/d8-allowed-changes#minor

#12 is still available with the string change.

Tested and verified the recent patch "taxonomy_term_reference_settings_form-2522950-12.patch" and taxonomy_term_reference_settings_form-2522950-14.patch both are working fine.
After applying the patch - 2522950-12 , "Create referenced entities if they don't exist" this option appears above the "Vocabularies" option. The string change from "Vocabularies" to "Available vocabularies".
For patch - 2522950-14: Same result without the string change. So now its easy to make out the settings for the 'taxonomy term' field type.
Screenshots attached.

Committed/pushed to 8.1.x, thanks!

We could commit the weight-only change to 8.0.x, but it's not a functional bug as-such so leaving as is for now.
