Feature description

In versions of the plugin prior to 2.0, there was an “Exit Reader Mode” link that could be displayed in the header. We removed this in #4573 because it conflicted with long site titles. We also deemed it redundant with the new Mobile Redirection functionality which shows such an exit link in the footer.

However, the exit mobile version only displays in the footer when Mobile Redirection is enabled. We should consider restoring the exit mobile version link when Mobile Redirection is disabled, especially when a site is in Reader mode. The link is probably not needed in Transitional mode because the AMP and non-AMP versions have much more parity. In Reader mode, however, the AMP version is intentionally streamlined so it makes sense that a user seeing the Reader version would always want to leave to go to the non-AMP version.

When mobile redirection is turned off, the link to return to the mobile version would not correspondingly be added to the non-AMP page.

This may require changing the Mobile Redirection section to instead be Paired Options, which could then incorporate the Paired URL Structure section.
