I've also had trouble getting rid of pop up menus (copy, etc). If I want to click on text, but it has decided to pop up a menu, it can be a real pain to get rid of it. (I had no problem on previous versions of IOS).
There's a fundamental law of features: Every feature you add may may make it better for people who use it, but it makes it worse for everyone else.
If you keep adding features, anything will eventually become unusable.
