Introduce a property to control whether the matching of the start and end folding tags is case sensitive or not.

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

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.

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

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 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,

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.
