Visited reports links should be "text-decorated" for user experience behaviour as 11.5.
FYI -- this has been added as an idea now: Visited reports in another colour (Report List)
I have spoken to Eloy and we have seen that there is another identical idea open
(Marking a report as browsed) so he has voted this Idea and has deleted the one he
opened with the title(Visited reports in another colour (Report List))
