Hello, everyone. There ara a little misunderstood, which I've resieved after spending some time working on a little bit more complex UI than I did usually. So my misunderstanding: what should I use to update from one widget to another: "Remove all widgets" or "Set widget visibility" or there is not much difference beetwen them in perfomance? 

If you want to use the UI again, you should use "Set widget visibility" and keep a reference to it somewhere (like the playercontroller). It's better for scalability.
