What is EsrCore?

EsrCore is a lightweight library addon that provides centralized font and status bar management for your World of Warcraft interface. Instead of manually changing fonts in every single addon, you assign fonts to reusable “slots” that can be used everywhere.

How It Works

1. Set up your font slots - Type /esr and assign fonts to slots:

Esr Font 1 = Your preferred font
Esr Font 2 = Another font
Esr Font 3 = And so on…

2. Use these slots in your addons - In WeakAuras, Details, Plater, ElvUI, or any addon that supports SharedMedia, simply select “Esr Font 1” (or 2, 3, etc.) as your font choice

3. Change everywhere at once - Want to try a different font? Just open /esr again, change what “Esr Font 1” points to, and type /reload. Every addon using that slot updates automatically!

Why Use EsrCore?

Save Time - Instead of hunting through 10+ different addon settings panels, change your fonts once in EsrCore

Experiment Freely - Try new fonts across your entire UI in seconds, not hours

Consistent Theming - Keep your UI cohesive by using the same font slots across all addons

Works Everywhere - Compatible with any addon that uses LibSharedMedia (WeakAuras, Details, Plater, ElvUI, DBM, BigWigs, and more)
