Use /oshs or /hitsplats to open settings. Use /oshs test for a hitsplat preview, /oshs interrupt or /oshs immune to preview those messages on your current target's visible nameplate, and /oshs reset to restore defaults.

The settings window controls outgoing and incoming damage visibility, interrupt messages, damage-school artwork, critical-number coloring, native Blizzard damage suppression, target-frame fallback, overall scale, text size, duration, offsets, and cluster spacing. It also controls the scrolling buff, debuff, and fade notification stream, including its icons, text size, duration, rise distance, and movable screen anchor.

Every spell school has their own colored damage splash. (Viewable in /Assets)

Healing is also separated from Arcane and Shadow damage with a tint.
