GrimmsUltrawide

GrimmsUltrawide is a modern fork of the original ZoxeTweaks, rebuilt for players running AtrocityUI on 3440×1440 ultrawide displays. It's built primarily around the AUI × EllesmereUI collab, but still fully supports the classic AtrocityUI + ElvUI setup for anyone running that version instead.

Ultrawide resolutions place unit frames, buff/debuff trackers, and other elements incorrectly by default — GrimmsUltrawide corrects the positioning, resizing, and scaling of these elements so AtrocityUI looks and feels the way it's meant to on a 21:9 monitor.

The addon includes three panels, so you only configure the one that matches your setup:

• General Tweaks — non-UI-specific fixes and QoL options: frame scaling (without touching global UI scale), an Auctionator tooltip fix, disabling automatic spell-to-actionbar pushing, and a minimap launcher button.
• AUI - EllesmereUI — tweaks for the EllesmereUI variant of AtrocityUI: unit frame repositioning, BigWigs bar resizing, font size overrides, larger chat/minimap panels, damage meter repositioning, and a one-click import of a pre-built Edit Mode layout to fix Buff/Debuff and Objective Tracker placement.
• AUI - ElvUI — the equivalent set of tweaks for the ElvUI-based version of AtrocityUI: unit frame fixes, BigWigs and Details! adjustments, font resizing, and a range of ElvUI-specific options (data bars, bag disabling, bigger panels, minimap data texts, tooltip tweaks, guild repairs, auto-accept invites) along with Plater nameplate font/scale tuning.

Tweaks in the EllesmereUI and ElvUI panels are applied via an "Apply Tweaks" button and need to be re-applied after each AtrocityUI update, since they write directly into those addons' saved profiles rather than hooking live. These profile-based tweaks are per-spec and per-character — you'll need to click Apply Tweaks once for each spec on each character you want them active on.

Designed specifically for the 1440p build of AtrocityUI. Access the addon via /gu or Options → AddOns → GrimmsUltrawide.
