Hi,
1) you will ahve to add code to your theme functions.php file to move things around. I’d suggest to have a look at this topic to get started: https://wpgeodirectory.com/support/topic/logo-for-listing-listing-details-page-stylemay-be-a-feature-request/
You will find plenty of example in the forum searching for something like remove_action (almost every customization start with that).
Other example could be:
https://wpgeodirectory.com/support/topic/hide-detail-sidebar/
https://wpgeodirectory.com/support/topic/detail-view-move-flexslider/
2) In Appearance >> Widgets >> GD detail right sidebar and adjust zoom in GD > Gmap Listing page widget.
3) same as above, disable sticky map from the same widget
4) see answer 1
Let us know how you went.
Also, should you need the help of a developer let us know and we will move this post to the Jobs section.
Thanks
