SmoothResourceBars replaces your default resource bar with a smooth, animated bar that works for every class. Mana users get spirit tick visualization, Five Second Rule tracking, and cast cost preview. Rogues get energy tick tracking. Warriors get rage tracking with queued ability cost display. Druids get a shapeshift cost threshold line showing if they can afford to shift forms.

Features:

Smooth Animation — Fluid bar interpolation instead of jumpy default bars
Spirit Tick Visualization — Shows the 2-second spirit tick cycle with a pulsing indicator; tracks Five Second Rule state
Shapeshift Cost Threshold — Visual marker showing if you have enough mana to shift to Bear/Cat/etc., accounting for Natural Shapeshifter talent reduction
Cast Preview Bar — Previews how much mana your current spell will cost before it finishes casting
Energy Tick Tracking — 2.0-second energy tick cycle for Rogues
Rage Mode — Warriors see queued melee ability cost (Heroic Strike, Cleave, Maul)
Health Bar — Optional smooth health bar
Custom Threshold Spell — Set any TBC spell as the cost reference line (e.g., Lifebloom, Chain Heal, Frostbolt) with /srb cost <spellID>
Built-in Spell Reference — /srb spells lists common TBC spell IDs
Public API — SmoothResourceBarsAPI global for WeakAuras and external addon integration
Options Menu — Configurable width, height, bar colors, tick alpha
Custom Font — Gill Sans Nova for a clean look
