When the caret position is inside Table and a page break is inserted, the table should be split into two tables with a page break between.

Add a property that can control whether a table row is allowed to break across pages or not.

RadRichTextBoxElement to be a custom editor of RadGridView

To reproduce:
Format a document with tables in MSWord. For example Insert a picture to the left and a table to the right. Import the document into RadRichTextBox. You will see that the formatting is not the same.

Add support for shapes, and especially for shapes with textual content. 
In OOXML, shapes are represented by the wps:wsp element, and shapes with textual content by <wps:txbx>, <w:txbxContent>.
Such shape can be added to a Word document using the Insert -> Text -> Text Box -> Draw Text Box, or through a shape's context menu -> Add Text.

Note: Do not confuse with Text/Rich Text content controls (http://feedback.telerik.com/Project/154/Feedback/Details/156478 )

Support for opening word templates in RadRichTextBox

ADD. RadRichTextBox - add support for line numbering

Currently it is not possible to control the HTML exported from RadRichTextBox and strip styles or embed them.

Improve redo-undo functionality of RadRichTextBox to allow removing a whole sentence or word by pressing CTRL+Z

When a table cell contains nested table, and the paragraph after the nested table is empty, this paragraph could be collapsed, as in MS Word. This gives better look to nested tables, similar to how browsers visualize nested HTML tables.
Note that the paragraph should be visualized when the caret moves the position inside the paragraph.

Currently the paragraph is visualized with its full height, making the layout different than MS Word - it appears that there are redundant space after the nested table.

IMPROVE. RadRichTextBox - should be able to run with .NET Framework 3.5, rather than 4.0

RadRichTextBox - add import from PDF file.

Provide functionality allowing a document to be thumbnailed. The customers should be able to export a document to an image.

Workaround: Use attached project. 

Html export of RadRichTextBox to perform font-size export in different units.

Case 2:
If you export a document using the HtmlFormatProvider, all style properties which contain measurement units are exported in pixel units. This makes the exported documents look much smaller when opened on devices with higher pixel density.

WORKAROUND: use Regex to find, convert and replace the font-size attributes

            HtmlFormatProvider html = new HtmlFormatProvider();
            string res = html.Export(document);
            Regex regex = new Regex(@"font-size: [0-9]*\.?[0-9]*px");
            Match match = null;

            do
            {
                match = regex.Match(res);
                if (!match.Success)
                {
                    break;
                }

                string value = match.Value.Substring("font-size: ".Length, match.Value.Length - "font-size: ".Length - "px".Length);
                double pts = double.Parse(value) * 72 / 96;
                res = res.Replace(match.Value, @"font-size: " + Math.Round(pts, 4) + "pt");
            } while (match.Success);

            File.WriteAllText("output.html", res);

ADD. Export of Office 2010 dotx document templates.

The customers need to convert the position to an integer number representing the offset of the current position from the first position in the document. A method returning the position at a specified offset would be useful as well.

Some voice recognition software (Nuance) is using integer positions as well.

In MS Word, MS RichTextBox and DevExpress RichTextBox, the positions are represented as integer numbers.
