I'm sure some people have been slightly bored dragging the slider bar to maximum for reagents or pet snacks, especially if your putting multiple things in or taking them out...a remove all button would help a great deal for moving a lot of different items at once, then sliding the bar, move, sliding the bar, move etc.
Re: add/remove all button on bank for reagents/snacks
What, how dare you suggest making an aspect of the game we all want improved and made more efficient and effective that everyone will love and appreciate for years to come!
I second this request! It would be awesome to have an easier way to buy and sell items with a feature such as this.
