add support for markup "markdown" in my opinion it would be very useful!

The fix is available in our latest LIB release (v. 2015.01.0413).

When ignoring incorrect words through the Spelling dialog and you reach the last word in the document which is incorrect, only one more word from the beginning of the document is checked prior showing a message that the check is complete. Instead, all incorrect words starting from the beginning of the document should be spellchecked. 

The issue is reproduced when adding the incorrect words to the dictionary. In order to reproduce the issue, only "Ignore" or "Add to Dictionary" action should be applied. When the actions are mixed, the issue is not reproduced.

Workaround: before opening the spellchecking dialog, move caret at the beginning of the document
this.radRichTextBox.Document.CaretPosition.MoveToFirstPositionInDocument();

The fix will be available in our official release Q1 2015.

As a result, table is visualized in RadRichTextBox with extremely large column widths.

Tap and Hold gesture does not work as expected.

The feature will be available in our official release 2015 Q2 .

The fix will be available in the next official release Q1 2015. 

RadRichTextBox's behavior is to reject/accept the whole revision where the caret or selection is. Modify the behavior so only the selected region is rejected/accepted and the rest is split into two revisions. Consider multiple selection ranges as well.

Custom Paragraph or Linked styles are not applied when used in Headers and Footers.

Left indent and hanging indent of paragraph in a list are changed when the document is exported to HTML and then imported.

Steps to reproduce:
- Add text.
- Apply list over the text.
- Export the document to HTML
- Import the exported HTML
Expected: The paragraph in the list preserves its left indent (18 px) and hanging indent (18 px).
Actual: The paragraph in the list is with left indent 18 px and hanging indent 0 px.

When HTML is imported it may contain invalid images. In such case show the alternative text if there is such text.

The CSS styling for the "p" selector is not imported as a "NormalWeb" style. For example the following:

<style type="text/css">p {margin-top:0; margin-bottom:0;}</style>

should be imported as SpacingBefore and SpacingAfter set to 0 in Normal (Web) style.

TabStopsProperties dialog is non-modal dialog, but it should be modal.

Implement Mirror margins similar to the option in MS Word.

In MS Word, this is controlled using Page Setup dialog -> Margins -> Pages -> Multiple pages: -> Mirror margins. Another possible options are 2 pages per sheet and Book fold.

Exporting document containing Hebrew text to PDF results in correct text (letter-by-letter), but with wrong text flow: letters in the words are inverted and flow left-to-right instead of right-to-left.
