## Description

Supremacy Utilities is an unofficial companion tool for the browser game Supremacy 1914. It runs entirely on <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/bdb9a4fd89daf512365b74a8f2f4c63f80dee302369e81465761126161af36a5/http%3A//supremacy1914.com" rel="nofollow">supremacy1914.com</a> and adds a set of in-game panels to help you manage your empire faster:

• Empire Overview — a consolidated dashboard listing every country, province count, and building breakdown across your empire in one screen, instead of clicking through each province individually.

• AI Relation Manager — view and bulk-update your diplomatic stance (war, peace, trade embargo, right of way, share map, share intelligence) with every AI-controlled nation at once, instead of setting each relation one by one.

• Distance &amp; Time Calculator — pick a start and end position on the map (or use saved army/city positions) to instantly calculate travel distance and travel time along the actual route, including speed differences between friendly and enemy territory.

• Combat Calculator — build an attacking and defending army stack, simulate the battle, and get a full round-by-round battle report (casualties, resources lost, cash lost, and hours lost) before you commit to an attack.

This extension only requests access to <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/bdb9a4fd89daf512365b74a8f2f4c63f80dee302369e81465761126161af36a5/http%3A//supremacy1914.com" rel="nofollow">supremacy1914.com</a> and its subdomains. It stores your saved positions/preferences locally using Chrome's storage API and does not collect, transmit, or sell any personal data. Supremacy Utilities is a fan-made tool and is not affiliated with, endorsed by, or sponsored by Bytro Labs.
