I organized my bank the hard way back in rsc (taking out all of specific items and redepositing) and really haven't done much since other than add in new additions to the skill to that general area slot. I have all items clumped together like my herbs, my armor, my potions, my food, ores, bars, and at the bottom is items I have 1 of or are random items from quests I dont want to toss, or that are useful in some way. I don't use tabs, really don't need to, my banks been the same since 2004.
