ShadowsOfUI-WarbandInventory

Adds a "Warband Inventory" block to item tooltips, telling you at a glance how many of an item your whole account is holding — and where.

Hover any item — in your bags, at a vendor, in the Auction House, in a chat link — and the tooltip gains a short breakdown:

• one class-coloured line per character that has any, with a (Bags: N, Bank: N, Mail: N) source breakdown (only the places they actually hold it). Characters on a different realm get their realm name appended, e.g. Kurorin (Norgannon),
• the shared warband (account) bank,
• each guild bank you can see,
• and a Total owned grand total on the bottom line.

Characters are listed most-first, capped so the tooltip stays small: up to sixteen names, then a +N more — /swinv <itemID> for the full list hint pointing at the slash command below.

Hold Shift to hide the block — handy when you want the plain tooltip (or are comparing gear, which Shift already does).

/swinv <itemID or item link> prints the same breakdown to chat for a given item — both a debugging aid and a quick "where is my…?" lookup you can run without finding the item first.

Dependencies

• LibNAddOn
• Warbandeer_Characters — provides the per-character bag/bank item counts this addon reads. (No extra scanning is added here; it surfaces data Warbandeer_Characters already collects.)

Notes

• Counts are last-seen. A character's bag counts update only while that character is logged in; bank and guild-bank counts update when you open that bank. So a freshly installed setup shows little until you've logged your alts in and opened their banks once.
• The warband bank is account-wide, so it's counted once (not per character).
• There is no window and no saved data of its own — it reads Warbandeer_Characters' cache.
