User Story:: As a user who uses Wikitext, he want to use the preview efficiently

Context of use:

• The user edits Wikitext, adds a reference and notes in the preview that the same reference has been used already. Then they want to reuse the existing reference.
• The user creates a link in Wikitext and they see that they got the formatting wrong (Wikitext syntax error).

Current Problems: The user has problems to match the previewed problem and the place where they can edit wikitext

Possible Solution: The user suggested the possibility to open the preview in a separate window
