Add an option to disable creating folder portals with alt click and drag

Hi.

In windows ctrl + drag creates a copy of an icon

shift + drag moves an icon

and alt + drag creates a shortcut of an icon. (you can also use ctrl + shift + drag)

when fences is enable dragging a folder with alt button creates folder portals instead of creating a shortcut, It's ok but I prefer to use alt dragging to create shortcut.

so I want to ask you add an option to disable alt + dragging to create  folder portals (there is still many ways to create it)

or add an option to disable folder portals completely.
