Settings
========

The ``/settings`` page groups a few preferences in three tabs. These settings
are **shared by everyone using the instance**: a change made here applies to all
users, not just to you.


Horizons
--------

A *horizon* is a named time window — a label with a *from* and a *to* date
expression. Horizons defined here populate the time-window selector used across
the interface (the quick view and the series editor), so a reader can switch to
a familiar range in one click instead of typing dates.

Timezones
---------

The timezone dropdowns throughout the interface do not list the whole timezone
database; they show a curated shortlist maintained here. Each entry is a
timezone name plus an optional friendly label. Add the timezones your team
works with and they appear in every timezone dropdown of the interface —
notably in the formula constructor and in the horizon widget.

Users
-----

In the pro version, the *Users* tab lists the instance's users and lets an
administrator set each one's role — **Reader**, **Editor** or **Admin** —
which controls who can read versus edit. See :doc:`security` for what each role
grants.
