Yes.
It's easy.
Open the file in plugin folder WidgetZones.xml
and remove this line
  <WidgetZone>productdetails_overview_top</WidgetZone>

Or another way to use CSS style
old

.fns-stickers-big-list {
}

.fns-stickers-big-list {
display:none;
}

Check if you use http or https in URL of store.

> 1. We are assuming that each picture can have a link (URL) to be set up when you click it.  Is there an option to define, for each picture separately, if the link will open in the same window or in a new (blank) window/tab?
In the same window.
You change the logic in the file PublicInfo.cshtml
But plugin doesn't have such parameter.
I think  if you need I can add it...

> Disabled people should be able to stop the slider from running, on both desktop and mobile.  Do you support this?
Can you explain me the problem or give me example?
I didn't add such feature.

> 3. Is there an option to design the navigation buttons on our own? such as small circles under the slider?
You can change the style of slider.
Plugin has CSS styles

You can try plugin free. Download and try.

I think that you didn't copy all (SQL files) before and plugin couldn't upgrade itself.

Can you backup live site and restore database to staging site?

1. Restore database.
2. Copy ALL files from new ZIP file and restart your IIS application pool.

Write me about result.
I wait.

Replace all files from new zip file and restart your IIS aplucation pool.
Do it and write me about result.

Download new release
http://foxnetsoft.com/content/files/foxnetsoft.feedmanager.zip

and try.
I couldn't check this feature because I don't have active Amazon account now.
If you can't upload the feed file than open plugin configure page and enable debugging.
Try to upload it again.
Send me plugin log file to my email support@foxnetsoft.com

> as I understand, the plugin looks at the Shipping method and checks for the string 'UPS' or 'USPS' or 'DHL' or 'FedEx'
If you enabled "Check Shipping Method from the order" than plugin will check Shipping method value.
If you disabled this parameter than plugin will try to check tracking number for all shipping carrier.

I'll do it. It's a good idea.
Thank you.

I did new release

Version 1.12 - January 03, 2019 (all nop versions)

+ added feature for USPS and UPS - removing spacebar from tracking number (plugin can check such tracking number 9999 9999 99999 ... too).

Plugin has JS file googleeehelper.js.

If your theme has original nopcommerce css styles than plugin can replace events.

Example
Plugin tries to find all 'Add To Cart' buttons using this JS code.

        //addToCart
        $('.add-to-cart-button, .product-box-add-to-cart-button').each(function () {
            var productid = GoogleEEHelper._getProductId(this);
            if (productid > 0) {
                $(this).click({ productid: productid }, function (event) {
                    event.preventDefault();
                    GoogleEEHelper.AddToCart('addToCart', event.data.productid);
                });
            }
        });

Yes and no.
Plugin sends customer's address to  Stamps.com and if this address is not valid then  Stamps.com doesn't create the label.
Stamps.com uses internal customer's address validation.
