Automatic Save Changes in Intervals in Local Storage

[idseefeld]

I think it might be a nice feature to store changes in regular intervals e.g. every 5 minutes in local storage.
In case someone closes the browser or the application crashes by unknown issue, you could show a button like "restore last changes". The related action will restore the form local storage.
When changes are successfully saved the local storage gets cleared until the user makes other changes.
Furthermore you could check if the node has been updated by somebody else while the current user tries to recover.
As far as I can see the change detection which should be triggered by leaving the current editor has not been implemented yet. Probably you could use the same functionality for this feature.
Just found save method in the core/stores/node.store. I think this might be the right place for such a method e.g. autoSave(data: NodeEntity[]) too.
