When browsing my issues, I often switch back to the
overview page and open the next or previous issue.

It thus would make sense to provide "next" and
"previous" - links on each issue page. Of course,
this is no trivial task, since what "next" and "previous"
means depends on the context (how are the issues
grouped, which filters are in use, etc.).

Anyway. It would be nice to have something like this.
