Description
Black Bar Adjuster (BBA) creates cinematic letterboxing by adjusting the WorldFrame viewport itself instead of placing overlay bars on top of the UI. Because the viewport is resized, no part of the game world is hidden behind action bars or UI elements, preserving full visibility while delivering a clean, cinematic look.
BBA is lightweight, dependency-free, and intentionally minimal. There are no draggable frames, no overlays, and no configuration UI. All changes apply instantly and persist across reloads and logins. The addon also ensures its viewport settings remain intact even when other UI systems attempt to reset the top of the screen.
Top and bottom viewport insets can be adjusted independently, allowing fine control over the letterbox effect or asymmetric layouts when desired. The result is a native-feeling presentation that avoids click-blocking, alpha tricks, or visual hacks.
