v4.11.0

[4.11.0] - 2026-03-14

Added

• ACTION_USABLE_CHANGED event integration — Event-driven slot usability cache in BlizzardAPI, populated by the batched ACTION_USABLE_CHANGED event (NeverSecret per-slot usable/noMana bools). GetActionBarUsability() now checks the event cache before falling back to the live C_ActionBar.IsUsableAction() API. Macro modifier effects are handled correctly: the C engine re-fires the event when a modifier key changes the effective spell on a slot, keeping the cache in sync. Cache is invalidated on slot content changes (ACTIONBAR_SLOT_CHANGED, page changes, vehicle/possess/override transitions).

Fixed

• Charge counts no longer disappear from queue icons when the related ability is hidden from the action bar (e.g. by a modifier-conditional macro). Charge text now uses C_Spell.GetSpellCharges directly (validated against secret values) for accuracy, falling back to the slot-based GetActionDisplayCount in combat.
• Local cooldown duration cache now re-scans on PLAYER_ENTERING_WORLD and after talent/specialization changes, in addition to combat exit. This prevents first-combat edge cases where un-talented base cooldowns were used for spells whose durations are modified by talents.

Changed

• Click-Through mode: grab tabs are now fully hidden, eliminating all dead zones. Hold Alt for 0.4 s to enter icon-drag mode — any queue or defensive icon becomes a drag handle. Brief Alt presses (modifier macros) are ignored by the hold threshold. Releasing Alt or finishing a drag exits icon-drag mode and restores full click-through.
