I remember when I used the feedback form I'd to translate everything with:

Sentry.showReportDialog({
    eventId: '{{ Sentry::getLastEventID() }}',
    user: {
        name: '{{ $name }}',
        email: '{{ $email }}',
    },
    lang: '{{ App::getLocale() }}',
    title: '@lang('It looks like we’re having issues.')',
    subtitle: '@lang('Our team has been notified.')',
    subtitle2: '@lang('If you’d like to help, tell us what happened below.')',
    labelName: '@lang('Name')',
    labelEmail: '@lang('Email')',
    labelComments: '@lang('What happened?')',
    labelClose: '@lang('Close')',
    labelSubmit: '@lang('Submit')',
    errorGeneric: '@lang('An unknown error occurred while submitting your report. Please try again.')',
    errorFormEntry: '@lang('Some fields were invalid. Please correct the errors and try again.')',
    successMessage: '@lang('Your feedback has been sent. Thank you!')',
});

(code taken from a Laravel Blade view)

Is that still the case?

@royduin I must say I have been doubting about all these settings if they should be included in the settings, WDYT each setting an admin field or one text area with a reference to the setting page?

A textarea injected feels a bit hacky but a field for every settings feels bloated. Maybe an additional template partial so it's possible to extend the settings from your own theme? Or maybe make them translatable as in my example? I don't know... @indykoning?
