Disable breadcrumbs of non-readable pages in the Panel

We have a blank.yml template in our project:

title: Blank
options:
  read: false

We use it to simply create “pages” in the content folder that serve as folders to better organize files (since having everything under content/* doesn’t work for us). Then, we have various sections around our blueprints that upload to these pages.

The problem is that you can click on the breadcrumbs to open those pages in the panel (shown in screenshot 2). When you open them, you just see an error telling you that the page cannot be found (screenshot 1). This is pointless - why give the user an option to navigate to an error? It’s a broken link, essentially. As far as we know, this is the only way the user could navigate to those utility pages and see an error.

It would be awesome if the breadcrumb is grayed out or something, indicating that it’s not clickable. Another option is to have a blueprint setting. For example:

title: Blank
options:
  read: false
  breadcrumb: disabled

And maybe breadcrumb: false could hide the breadcrumb completely.
