Request for improvements in SiteNavigationElement schema generation

I am using the SASWP plugin to generate SiteNavigationElement structured data from my WordPress menu.
I noticed two issues that could be improved to make the schema output more compliant with schema.org and Google’s guidelines:

1. Unique @id values
   Currently, all SiteNavigationElement items are generated with the same @id (for example https://domain.com#Main).
   This causes multiple elements to share the same identifier, which is not valid JSON-LD practice.
   Suggestion: please generate unique @id values for each navigation element, for example based on the menu item slug or URL (https://domain.com#nav-notebook, etc.).
2. Relative URLs
   The plugin outputs relative URLs from the WordPress menu (e.g. /notebook/).
   According to schema.org recommendations, URLs should be absolute.
   Suggestion: normalize all links to full canonical URLs (e.g. https://domain.com/notebook/).

Both of these improvements would make the structured data cleaner and reduce potential warnings in Google’s Rich Results Test.

Could you please consider adding these enhancements in a future release?

Thank you for your support and for maintaining this plugin.
