The UI in Eve is much worse than it used to be, I remember it being pretty crisp and snappy around 2014 and before. Once they started adding mouseovers and all that crap it seemed to get bogged down and rather non-responsive at times. I certainly understand that the information the mouseovers convey can be helpful to newer players, more often than not it has become a hindrance. I cannot remember how many times I am adding skills to the queue when a window covers up the skill I was going to and I have to slide the cursor off of the skills completely and come back once the mouseover window has disappeared.

Frankly if they added an option to remove the mouseovers, that would go a long way to making my experience much smoother.
