This is an exelent tool that I use my self a lot.
Have you ever found yourself looking for that darn treatment rifle, you know it is on one of your chars, but not sure which? Than look no further, if you keep IA running in the background when playing AO, it will keep track of where all items are once you are synced up. Whether it is in the bank, in a backpack, or a backpack in the bank, IA will help you find it with it's searchable local database.
It's just one of those tools that you can't imagine living without once you have tried it.
Contact information to the developer is listed on the bottom of the page linked to above.
