WhereLoot lets you browse all current season loot in one place (dungeons, raids, and world bosses) without clicking through the journal one by one.

Type /whereloot or /wl and instantly load every item available for your class, spec, and slot, then browse by slot, stat combo, and even see M+ drop tooltips and great vault M+ items too.

What it does:

Shows loot from all current season dungeons, raids, and world bosses in a single scrollable grid
Auto-detects your loot spec, you can click the top bar to switch specs instantly
Displays all difficulty tiers side by side: Dungeon N/H/M/M+, Raid LFR/N/H/M
Color-coded based on crest used to upgrade.
Includes a seasonal item level reference chart, top right
Includes Vault Mode top right also
Adds a WhereLoot button to the Adventure Guide

Navigation:

Click any slot in the horseshoe layout (roughly mirrors your character pane)
Click the slot bar to switch slots without going back
Click one stat to show items with that one stat
Click two stats to show items with that stat combination
Click Vault Mode to see Great Vault ilvl for the relevant dungeon levels.
Click iLvl Chart to see the item levels of things in the season
Right-click to go back or close
Resize the window by dragging the bottom-right corner

Bugs/Testing:
I only have one character, and this is the first proper addon i've ever made, but I have an accept-no-compromises approach to design, so please let me know anywhere with bugs/concerns/feature requests.

Special thanks to Dex, Elm, Ruger, Panso, Trinkz, Gabe & Drinx, for help with testing and feedback.

Lightweight by design, this is the highest priority.
ll data is pulled live from WoW's Encounter Journal API.
Zero taint, zero combat interference, hopefully zero lua errors.

Updated for WoW Retail Midnight (12.0.1)
