GroupHug is a purpose-built healing-frame addon for modern World of Warcraft, designed around Blizzard's current secure API model instead of brittle old workarounds. It supports click-to-heal bindings, premade profiles, debuff and buff tracking, absorb overlays, hover keybind tooltips, and healing-focused frame behaviour that stays usable under current Secret Values restrictions.
The standout work here is UI logic under strict game-client constraints: SecureActionButtons, modifier-aware binding systems, triage sorting, dispel indicators, buff-color overrides, absorb rendering, and per-spec profile state all have to behave predictably in a restricted environment.
It is a strong technical example of substantial addon engineering with both gameplay and UI complexity.
