Feature Request: Delete multiple layers in Fabrik

As of now, we can delete one layer at a time. We have to select the layer we want to delete and scroll all the way to the bottom to delete the layer.

It's usually a hindrance if you want to make lots of changes to your network, but also do not want to clear everything.

A good solution would be to introduce an option to select and delete multiple layers. Please be sure to update parameter count and other relevant attributes accordingly.
