We could introduce API for customizing the folding region lines and their respective regions. For example, a customization could be hover-coloring of line regions, like in the latest VS:

Bug Report
The CSharpTagger matches the following character combination as a multiline comment start - / * (slash and a start with a whitespace between). This causes wrong tags creation in scenarios where the * character is a part of a single line comment. The correct comment start and end should be /* and */.
In the following example, the beginning of the first single line comment is considered a multiline comment start, but since nothing closes it, the entire text is tagged and colored as a comment.

Bug Report
NullReferenceException thrown on opening the CompletionListWindow when RadSyntaxEditor is hosted in a non-WPF application (usually WinForms) and there are no WPF Application and MainWindow initialized.
This can happen if the RadSyntaxEditor for WPF is hosted in a WinForms application. In this scenario the System.Windows.Application.Current and its MainWindow are not initialized, which is what the IntelliPrompt positioning logic relies on.
Exception details:
System.NullReferenceException: 'Object reference not set to an instance of an object.'
