CastHistory

A horizontal timeline of your recent casts with GCD reference markers. Inspired by the cast-history view in the Details! Streamer plugin.

Features

Live timeline of every spell you successfully cast — newest at the "now" edge, scrolling away as it ages out of the configurable time window.
Reference markers for the base 1.5s GCD and your current haste-adjusted GCD, so you can see at a glance how tight your cast cadence is.
Configurable growth direction: timeline can grow Left, Right, Up, or Down.
Overlapping casts (e.g. an off-GCD ability fired right after a GCD spell) stack vertically so both icons stay visible.
Optional diagonal spell-name labels under each icon.
Full Blizzard Edit Mode integration via LibEditMode:
- Drag to reposition from inside /editmode
- Snaps to the Edit Mode grid when "Enable Snap" is on
- All key settings (time window, icon size, max icons, alpha, growth direction, frame strata, GCD markers, spell names, background) live in the right-click selection dialog
Configurable frame strata so the timeline can render above or below other UI.

Slash commands

/casthistory or /ct — open the config panel
/ct show / /ct hide / /ct toggle — show, hide, or toggle the timeline
/ct clear — clear the on-screen history
/ct config — open the options panel

To move the frame: open /editmode, click CastHistory, drag.

Known limitations

WoW patch 12.0 ("Midnight") restricted addon access to COMBAT_LOG_EVENT_UNFILTERED, so auto-attack swings cannot be tracked. CastHistory shows only spells/abilities that fire UNIT_SPELLCAST_SUCCEEDED — which is everything the Details Streamer cast-history reference relied on anyway.
