5a:T4d6,

A lean, opinionated world-buff tracker for WoW Classic Era — tracks world buffs across every character on your account, with live countdowns and Chronoboon awareness.

Heads up — this is a personal work in progress. I build and evolve it as I play, so features land when I need them, design choices reflect my play style, and things may change between releases. Feel free to give it a whirl and leave me some feedback, but don't expect changes that fit your play style if it doesn't fit mine.

Caveats

Only works on Classic Era, no support for other game versions.
Tracks the canonical world buffs (Rallying Cry, Spirit of Zandalar, Songflower, Warchief's Blessing, DM tributes, DMF Sayge's Dark Fortunes) plus the Chronoboon meta-aura and its stored contents.
Scoped to the connected-realm cluster you're currently logged in on; characters on unrelated realms don't show up.
Two optional filters in the window footer: hide below-level-60 characters and hide opposing faction. Settings persist per cluster.
