Currently PdfFormatProvider does not use the track-changes styles when exporting the document. So the different text color, underline, strike through or borders will not appear in the exported PDF.

Implement IF and ASK fields.

Consider raising an event when the images are finished loading, or an option for loading the images synchronously. 

When the caret is positioned in the beginning of a paragraph and a table is inserted, an additional paragraph before the table should not be added. This also includes the case with a blank document.

Special case: When there is a table in the document, inserting another just after it should be disabled.

Currently UI code generated by RadRichTextBox wizard is not localized out of the box. Add support for easier localization.

Provide mechanism for selecting an uri from which a dictionary can be downloaded when needed. In this way the client will download only the dictionaries that are in use. If more are needed, they will be downloaded on demand.

This field retrieves a character through a code value specified in the field-argument. Such documents are common and are created when symbols (e.g. with font Windings through Insert -> Symbol dialog) are inserted in RTF documents in MS Word. 
This functionality is also used when content containing <sym> element is copied from DOCX and pasted in RadRichTextBox - as the content is converted to RTF containing SYMBOL field during the operation.

Workarounds: 
- Implement such field with the API, see the documentation article (http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/features/fields-and-document-variables/custom-fields ) and the SDK example (https://github.com/telerik/xaml-sdk/tree/master/RichTextBox/CustomField/ ). Note that MS Word doesn't show field menus for these fields in RTF documents.
- If RTF format is used and you have control over document creation, save the documents initially as docx, and then save them to RTF. This way the symbols will be encoded without the SYMBOL field construct, and are successfully imported in RadRichTextBox.

Available in R3 2018 Official Release.

In MergeFields the general switch may be used to format the Result Text. The text may appear in lowercase, uppercase, title case and so on.

In some text editors (e.g. Visual Studio code editor), pressing the Insert button activates overtype mode, where characters are typed over the current ones (the current character is deleted before the new one is inserted). This is not supported in the modern versions of MS Word.

Support (programmatic and non-programmatic) for Word-like real-time text correction and formatting (similar to AutoCorrect and AutoFormat).

Font weight, size and other current editing style properties are not preserved when document layout is performed, for example in the following cases:
- the document is in web layout mode and the controls is resized
- scroll bar changes its visibility.

Steps to reproduce:
- Set RadRichTextBox to Web layout mode.
- Type a word, select it and make it bold.
- Press enter and type a word
- Repeat the previous step until RadRichTextBox height is reached and scrollbar appear.
- Type a word.
Expected: The last word is bold.
Actual: The last word is not bold.

Floating table are tables that can be absolutely positioned in the document, with different text wrapping (similar to floating images). MS Word converts a table to floating object whenever the table is dragged.

Add options in Table Properties dialog similar to MS Word – Table with Text Wrapping: Around and None.

Add support for DeletePreviousWord and DeleteNextWord commands, triggered with Ctrl+Backspace and Ctrl+Delete keyboard shortcuts.

Add support for optional (a.k.a. soft) hyphens. In MS Word, such are inserted using Ctrl + -. If the word need to be split as there is no enough space on the line, the word is split after the optional hyphen.

The same issue is observed with heading styles. 
The HtmlExportSettings property PropertiesToIgnore can't be used to control how the paragraph or character properties of a list will be exported.
Steps to reproduce:
Create a document with a list of different levels.
Set fp.ExportSettings.PropertiesToIgnore["li"].Add("margin-left");
Export to HTML.
Observed: The PropertiesToIgnore doesn't work for paragraph properties of a list.

DeleteTableRowCommand and DeleteTableColumnCommand should be able to delete all selected table rows/columns at once. Currently, the command cannot be executed when there is selection and  the user should delete the rows/columns one by one.

Implement the export of notes (footnote, endnote) in the PdfFormatProvider of the RadRichTextBox.

Create UI for editing CITATION fields, a.k.a. "citation placeholder", which later you can edit. 

Currently invalid attribute values, including invalid or empty values in CSS attributes in the 'style' attribute, could cause importing property with incorrect value, or NullReferenceException (the document cannot be imported).
Examples:
----------------------------------------------------------
<table width=”*”>
	<tr>
		<td>More Random Text</td>
	</tr>
</table>

The table is imported with 0 width. Instead the width should not be set.
----------------------------------------------------------
<table style="font-size:;">
	<tr>
		<td>More Random Text</td>
	</tr>
</table>

NullReferenceException is thrown.
----------------------------------------------------------

Workaround: replace the invalid values before import:
string importString = html.Replace("font-style: ;", "");

Add Paragraph property controlling  whether SpacingBefore / SpacingAfter is applied between paragraphs with the same style.

In MS Word, the corresponding option is controlled with "Don't add space between paragraphs of the same style" checkbox in the font properties dialog - and the paragraph spacing after will not be applied. 

In OOXML, it is described with the w:contextualSpacing element. We don't respect this property on import of such files, and the paragraph spacing is bigger.

Common use case for this feature is that when list is applied to multiple paragraphs, Paragraph List style is applied to the items, and this style has "Don't add space between paragraphs of the same style" applied, so the vertical spacing between the items is smaller.
