that little +1s or w/e that pops up under the material cost when I click on buy is annoying as hell because it makes the buy/sell buttons move down ever so slight for a short bit. I would be able to tell you what it is but it's like a dark orange ontop of a dark brown. so I can't really read it. see previous comment about colors.
to be frank, that's not an experience popup, it looks like a cooldown, becuase it typically appears as ~#/s and decrements don't to 0. Then the buy & sell buttons move back up in to normal place. I recommend the cool down move to the side of... or in-line with the material cost of the item. Or be embedded in the buy button itself.
