Is there actual feedback that people prefer to click and wait for a repl to run rather than see what is expected immediately?

@marin-bratanov, In the kendo-themes release they changed the primary colors of the charts, thus all screenshots are wrong. That and the situation with the component options (we will release them with one visual, but they will change right in the next release) led us to conclude that having so many screenshots in the docs is not feasible. So we will gradually remove all screenshots, apart from the ones that explain the structure of the component (as in StockChart, ColorPicker, etc.).
