[feature request] "get" the application from the stage manager by dragging the cursor from the icon

[Katr1nge]

Now you can drag only one application from one stack - the one for which a preview is shown, and it is impossible to drag all the others from one stack to another
(example screenshot of how this could potentially work)

Also, I would like that if you drag an application to the left side where the stage manager is located, you could place the application in a specific stack
