Option to display all endpoints on a single page

Is your feature request related to a problem?

We would like to display all endpoints for an API on the same page, so that users can both select an endpoint from the TOC (sidebar) and scroll all endpoints without selecting (e.g. for mobile devices and small screens). This layout is becoming standard - used on GitHub docs.

Describe the solution you'd like

When generating the Markdown files of a Swagger, provide an option to automatically merge all files for the same swagger into a single Markdown file, so that all endpoints for that API are on a single, scrollable page.

Describe alternatives you've considered

Other open source plugins, such as Rapidoc, Slate, Redoc, have an outdated layout, without the great layout provided by this plugin.

Additional context

We love the layout that we get from the plugin but we're getting user requests to provide all endpoints for an API on a scrollable page.

No implementation files or tests are named. Start by locating the Markdown-generation path for a Swagger and trace how endpoint files are produced. Done means an option can merge all endpoint files for one API into a single scrollable Markdown page while retaining endpoint selection in the sidebar.
