Is "Hide offer" function cancelled, or is it not working?

I used to work with plain horrible programmer on some project a while back, where every fucking single time some modification to the script is made by him, some other feature on the site get's screwed up and stops working or is malfunctioning, because of the new change introduced. The worst part is that when the site is heavily multifunctional, there is no way to know which feature gets screwed, until one tries to use it. It was really becoming a nightmare when these secondary issues were getting "fixed" and thus the troubles where just mounting at a snowball rate, with every next fucking "fix".  I really hope this is not the case at Bitfinex, I honestly do!!!
