It is now also possible to insert layers from Web. When you are going to add a new layer, you can now also choose to insert a layer in the pop-up that you get.
You can do this by clicking on the dropdown in the pop-up at the “From”. You will then see a list of all layers. Here you can choose the layer from which you want to insert and then fill in the new ‘To’
This is possible in both tile and table view.
