Cant find drag arrow tools in elements in WixStudio

Hi, I am now using WixStudio, but I cant find important tools that use to be in the regular editor. The most important for me is drag arrow that appers in every element that allow you to drag down with all elements above.

Here area pictures of it

Thanks,
