Feature Request: Primary Category Support + Global Separator Option

I really like the Breadcrumbs Block plugin, it’s simple and clean. I’d love to request a feature that would make it even more useful for agency setting:

1. Primary Category/Taxonomy Control
   It would be great to have the ability to set a primary category or taxonomy term per post (or inherit from something like Yoast or Rank Math’s “primary category”). Right now, it defaults to the first taxonomy term in the list, which isn’t always the one we want displayed in breadcrumbs.
2. Taxonomy Selection / Disable Option
   Ideally, users could choose which taxonomy to include in the breadcrumb trail — for example, “category” vs. “custom taxonomy.”
   There should also be an option to disable taxonomy display entirely (e.g., show only “Home → Page”).
3. Global Separator Setting
   The ability to define a global separator in plugin settings would be great for consistency across all Breadcrumbs blocks.
   The per-block override could remain (for flexibility), but having a single global setting would prevent repetitive configuration.

These changes would make the plugin much easier to integrate into larger sites and improve workflow for developers managing multiple content types.

Thanks for considering these requests, I really appreciate the work that’s gone into the plugin so far!
