LayerTree changes are not getting saved into the file

[martinRenou]

See #22 (comment)

The changes on the tree are propagated to collaborators, but not save in the file. In a regular usage (new layer and layer included in tree), it works well because the new layer trigger the change on the server side. But if we only include a layer in the tree, it is not saved in the file. @davidbrochart any thoughts on this ?

Actually I can't reproduce, I can see the layerTree being properly updated:

Yes, I observed this when doing some tests modifying only the layer tree, and not the layers and sources.
We will soon add a way to move the layers in the tree (without changing the layers and the sources), we'll see if the issue is still relevant.

I guess the kind of UI we'd want is being able to select multiple layers then right-click -> group selection, we'll need a context menu in your tree widget.

This context menu will be useful later for other commands.

Yes, the context menu is a good option to create groups from layers.
We probably also want drag and drop to move the layers individually.

Closing as it actually works
