The addon allows to disable weapon swap at any time:
Lua Code:
LockWeaponSwap.Lock('Cloudrest_Voltaic_Overload')
LockWeaponSwap.Unlock('Cloudrest_Voltaic_Overload')
Currently it's only useful in Cloudrest. When enabled, the addon doesn't allow you to swap weapon bars, while Voltaic Overload effect is active (after the first swap, of course).
Note: the addon only disables "Weapon Swap" key, there are still other ways to swap bars, which haven't been changed.
Tested for API 100033 (Markarth), can't guarantee it'll work in future updates, because currently there is no a "clean" way to disable weapon swap.
