With modifications, it can be very useful

This plugin is very good. But it has a very big problem.
This plugin only detects headers for sites that have a simple header.
For example, some themes have separate headers and footers for mobile.
Or they have a separate header for the checkout page or cart.
In these cases, this plugin does not work. Like the Woodmart theme.
It would be great if this plugin had settings, which received the URLs of headers and footers, or their folder address, and cached them.
But alas …
