Is there any way I can detach individual settings tabs to be their own windows in Blender 2.8 rather than it being stuck within the interface?
There is non, as far as I know properties windows tabs are not detachable.
But nothing stops you from having multiple of them open. As a workaround just duplicate the window and change active tabs on each instance.
Just press Shift while dragging from one of the corners to create a new secondary window and change tabs for each
Right click on the panel then select duplicate area into new window. Of course after this you can merge the old panel with others in the main window, by right clicking on the separation line between them, and select join area.
