A week ago I rejected a request at Redmine#1514 by Samuel Mehrbrodt. He requested a change in the wiki configuration so that double clicking on a text in the wiki don’t bring you to the edit field of that section. I rejected the ticket because there is an option in the user preferences to disable that “feature”.
As Florian suggested I started a thread at the website mailing list requesting more input (see archives if you are not subscribed). Feel free to comment either at the website mailing list or at the Redmine ticket.
PS: I have added a new FAQ page how to create a page containing an OpenStreetMap map.
