> User may think that he is blocked or did something wrong, on one of wizard (any wiz) steps because Next button can be disabled (on significant time), especially on big clusters or in case of slow connection speed, or bad ping. 
> We have many places where we disable "Next" button while we do some background operations/calculations. Usually this are requests on validations/recommendations. Sometimes this can take a significant time frame, before we will enable Next button. At the same time user is not aware why Next button is disabled and he cannot proceed to next step. We should give user a visual feedback that we are doing some calculations and that's why Next button is disabled. The easiest way is, to switch Next button on spinner while we do our background stuff.
