Customer requirements

1. We've a menu entry type "Location search & display" with theme "simple" (the customer prefers this view). Is it possible to search for the location "name" in this theme also (like it is in the theme "full width")?
we need customization to do this and yes we can support this in your case.
2. When I put a german zip code like 01099 all street numbers of the world are listed as suggestions in the field. Is it possible to restrict it to (german) zip codes?
That cannot be done.
3. On the location card and on the detail view of the location we need to display the mail adress and website url directly (not as icon and link) (see screenshot). Is this configurable?
Yes this can be done by overriding helper code.
4. Where are the language overrides? I can't find for "Verwenden Sie Ihren Standort".
Please create a ticket so we can check this.
