Hi Dimitr, im finding this package very useful.awesome job.

I've extended it to create translations for child nodes, hope thats ok:

• Added a radio list to the create page ("apply to immediate child nodes", "apply to all child nodes", "only current node")

<asp:RadioButtonList  ID="ApplyToChildNodes_RB" runat="server" >
    <asp:ListItem Selected=True >Only Current Node</asp:ListItem>
    <asp:ListItem >Apply to Immediate Child Nodes</asp:ListItem>
     <asp:ListItem>Apply to all Child Nodes</asp:ListItem>
                </asp:RadioButtonList>  

• Tweaked "TranslationCreation.aspx.cs" as follows:

private void save_Click(object sender, ImageClickEventArgs e)
        {
            string saved = "";
           
            if (ApplyToChildNodes_RB.SelectedItem.Text == "Apply to Immediate Child Nodes")
            {
                saved =  ApplyToImmediateChildNodes(_nodeID);
            }
            else if (ApplyToChildNodes_RB.SelectedItem.Text == "Apply to all Child Nodes")
            {
                saved =  ApplyToChildNodes(_nodeID);
            }
            else
            {
                saved = createTranslation(_nodeID);
            }

            Response.Redirect(_queryString.BeforeUrl + "?NodeID=" + _nodeID.ToStr() + "&saved=" + saved);
        }


        private string ApplyToChildNodes(int Node)
        {
            var doc = new Document(Node);

            if (doc.ChildCount > 0)
            {
                foreach (Document child in doc.Children)
                {
                    ApplyToChildNodes(child.Id);
                }

            }

            return createTranslation(Node);


        }

        private string ApplyToImmediateChildNodes(int Node)
        {
            var doc = new Document(Node);

            if (doc.ChildCount > 0)
            {
                foreach (Document child in doc.Children)
                {
                    createTranslation(child.Id);
                }

            }

           return createTranslation(Node);
        }

        private String createTranslation(int node_id)
        {
            var saved = "ok";
            if (DocumentTranslation.GetTranslationFolderContentType(node_id) != null)
            {
                try
                {
                    if (!DocumentTranslation.TranslationFolderExists(node_id))
                        if (!DocumentTranslation.TranslationFolderCreate(node_id)) throw new Exception();

                    if (CheckBoxList1.Items.Cast<ListItem>().Where(li => li.Selected).Any(li => !DocumentTranslation.TranslationNodeCreate(node_id, li.Value)))
                    {
                        throw new Exception();
                    }

                    DocumentTranslation.SortTranslationNodes(node_id);
                }
                catch (Exception ex)
                {
                    saved = ex.Message == "NoLangProp" ? "NoLangProp" : "failed";
                }

               
            }
            return saved;
        }

It works as it should but i might have overlooked something and possibly write the code better. But the idea is probably worth putting into a next release? What do you think?
