Foldings are incorrect when there is a missing open or close tag.

I do have some feedback on this component. I love it, but of course there are some areas where improvement can be made. For instance, in the screenshot below, I have highlighted some words where improvement can be made.

1. ‘1,2,3,5’ – Literals in SSMS are Red
2. ‘ER – 100% OF MEDICARE’ – OF is highlighted in Blue. It is contained in a literal and shouldn’t be highlighted
3. ISNULL – Is a function and should be highlighted in Blue

---- - It looks like that the tagger is only looking for 2 – only. If there are more than 2 in sequence, it doesn’t identify it as a comment and should

We could create intellisense similar to Visual Studio.

'Cannot find resource named 'DragVisualStyle' error occurs in in the error list when using implicit styles.

Add support for using right-to-left characters. This includes.
    - typing from right to left
    - proper selection, navigation between RTL chars
    - proper insert, delete, cut, copy, paste operations (modifications) sign

A message could be shown when using the Find mechanism, and you reach the end of the file or the starting point of the search. 

Python is one of the most important scripting languages. It would be nice if this language was supported by default.

Add dependency property for showing/hiding the line numbers on the left of the source code.

If you have an XML attribute with a string value, but the value is not fully rendered into the viewport, its color defaults to black, instead of the expected blue color.

To work this around, you can create a custom XmlTagger and override its GetTags() method. This will allow you to properly catch the string value and return it as a tag span element with its ClassificationType set to "string".

Add separate folding tagger class for creating folding (collapsible) regions in XML, XAML, HTML code files.

Add ability to disable horizontal scrollbar and enable word wrapping - fixed width of editor and if the word cannot fit - it is moved to next line.

Hello,

We would like to use SyntaxEditor by providing our own programming language definition. It would be great to have the ability to feed SyntaxEditor with a language definition file. This file could be use an EBNF-like format to provide syntax coloration.

Thanks & regards,

Folding tagger does not work for other languages than C#.

For example "//====" will not be commented in C#. 

Add API for inserting code snippets like in Visual Studio.

Adding breakpoints (markers) to particular lines in code should be possible.

Should be doable via UI or in code. Collection of all breakpoints should be accessible in code too.
