I am always annoyed by etherdelta's user interface. It is hard to use usually in mobile device and hard to scroll down especially when buying or selling. Unlike other trading sites have good UI. I can't stop using etherdelta because most of my tokens are only tradable in their slow site.
if you really cant stop using it, them be patient everytime you use it. I stopped using it because I encounter a lot of issues, my wallet was hacked, its site is really slow, and there's a lot of dumpers.
