Hello Den,
yes the drag and drop icon are meant to work.
When you are holding the windows, the icon should show up, sometime it takes a few second or you need to hold and move the windows around then it show.
And I'm not sure what you mean by " [1] and [2] options ", do you mean the two icon is now replaced by number 1 and 2? then if you still use the 1 and 2 like drag and drop, does it work like drag and drop?
Thank you.
