Is there a simple way to alter core node/add/my_node_type to adding/my_node_type? I don't want to show "node/add" in my url "node/add/my_node_type", instead I want to have "adding/my_node_type". Is there a simple way to hide "node/add" but not loose those args?
I want to have "node/add/my_node_type" functionality after hitting "adding/my_node_type".

I can't see form add or form edit patterns in path so I think it is not so easy...

Of course after that I will need "node/%/edit" to be "editing/%"...
I didn't test this code, but if I'm not mistaken, it should be as simple as doing this in a custom module:

function YOUR_MODULE_NAME_menu_alter(&amp;$items) {
  $items['adding/my-node-type'] = $items['node/add/my-node-type'];
  unset($items['node/add/my-node-type']);
}


Something similar could be done for the editing path.
