Please consider to add this feature:
How about enabling a feature in which you can hit "Control" button on your keyboard and then left click on multiple boxes / elements and then move them around using your left mouse.
Analogy: You know like in Microsoft Powerpoint, you can hit your keyboard: “Control” + then you left click on multiple items to choose them then you release Ctrl button and use your left mouse to move them around or you can choose multiple elements at the same time then perform functions like Ctrl + C, etc.
Thank you kindly!
