StorageDiscovery works with the original Blizzard inventory bags, guild bank, players bank, characters frame, inspection frame... (did i missed one?)
You can type in a little search text under your backpack and that name will be searched in your bags. The items with a matching name get highlighted.
StorageDiscovery has been married with the oGlow procedures because one function have been missing there: make a clear frame around quest items. And also has been merged with that project because i find them both usefull.
