EJSI adds mouseover tooltips with full descriptions, Spell IDs, and Icon IDs to the abilities section of the Encounter Journal making it quick and easy to create WeakAuras for relevant mechanics without having to remember spell names or IDs mid-encounter.
Additionally, EJSI marks Private Auras in the Encounter Journal, to indicate when WeakAuras and other addons will be unable to interact with those particular buffs, debuffs, or spells.
EJSI works with both the current live Encounter Journal as well as the upcoming Patch 10.2 releasing on November 7th.
