The settings shell verified
The frame that holds the sixteen settings sections, each a hash route of its own.
In detail
A single module with sixteen routes — #/capacities, #/schedules, #/floodpatterns, #/responsepatterns, #/rewrites, #/suppression, #/paused, #/errors, #/ippools, #/externalmtas, #/dkims, #/mxpatterns, #/iprangegroups, #/localemail, #/restapi, #/config. Each opens a slide-over panel rather than a page, which is why the browser's back button and a copied URL both work: the route is in the hash. For a control module the practical value of this list is that it enumerates everything an operator can change on a node without touching a file. Fifteen of the sixteen write the cluster database; the sixteenth displays the configuration file.
