I like your idea, though: Instantly when I saw your withdrawing button idea, i noticed it could do with a bit of improvement. I think we should be able to customize those buttons by right clicking, then using an option like "change value" and we would need to enter the number with the keyboard.. this could be useful for herblore, fletching etc, where you know the amount of an item you want to take from the bank each time, so you can set the button to withdraw 14 or 28 automatically. Options of 1, 10, 100 do not really help.. it would be better if we were able to customize them completely, by typing in our wanted number. Also, all the buttons could be a bit smaller, so they would not take as much screen space. Another idea - i understood that in your idea, to move an item from one category to the other (eg. from mining to fishing), you would need to use a special "bin" slot. this is not efficient. It would be less clicking if you could just drag an item from the visualization area over the wanted group name, then when you click on the name, the new group opens. The item you're moving is "attached" to your mouse. Then, when youve opened the new group you move the item to the slot you want to place it in and click once more. Other than that, its perfect :)
