You have quite a few alts and you like to play all of them. However, you don't want to login to one to just check if they have a certain item that you know all of your characters collect. Just as an example, Badges of Justice.
The mod in question i am suggesting is two parts.
One part will let you add an item to a whitelist and it will store and update information about that item. If you added Badge of Justice, you'd know that one character has 20 and another has 30 or so. You can then view a list of these items... somewhere, and how many of them total and per character. It would also show something similar in the item's tooltip, showing who has how many of that item. One feature of this would let you specify a character as a bank and also track their guild bank, if available.)
The second part is to track when you mail things between your characters. (One thing that annoys me about MoneyFu is that if i mailed money to an alt, it counted it as money gained and lost, thus giving me a retarded amount gained/lost/profit. Yeah I totally made 14k in a week.)
While there are addons that show off the entire bank/inventory of your characters, I really am not interested in how many bullets my hunter has or how pretty my warlock's hearthstone is.
After thoroughly checking it out, Bagnon is pretty close what i'm looking for. While I personally just don't like seeing my other character's entire bags (and it doesn't show or track guild banks), the tooltip thing is a nice bonus.
However, what if i don't have the item? I keep all my primals on my bank, and most of my cloth and stuff in the guild bank. There should also be something for that
both Mendeleev and Bagnon/Banknon add alt quantity information to item tooltips, how is that insufficient?
Since when did Mendeleev do this? :P
@Tapeta: Bagnon is the actual bag mod. Bagnon_Forever is the module that saves the items so that you can view the actual bags themselves through Bagnon (your bank alt's bank while you're on your main, f.e.). Bagnon_Tooltips is the module that adds the Bagnon_Forever info to your tooltips.
