Hi Tobias Riley,
We have added Word-like tab stops as a future enhancement to the control, but I cannot provide you with a specific timeline of when they will be implemented.
As for tabbing out of the control using Tab and Shift+Tab, this is possible by setting the AcceptsTab property of RadRichTextBox to "False". In that case, pressing Tab and Shift+Tab will move the focus to the other controls on the page instead of changing the indentation of the paragraphs.
I hope that answers your questions.

Do you want to know when a feature you care about is added or when a bug fixed?
