Thanks for taking the time @band-a-prend to test it. As you pointed out the style matters !! or !>. The problem is that FORD documentation can look a lot like Doxygen, so creating a parser that works for both is rather tricky.
I will have a look at the stdlib examples you mentioned and see what can be done.
I will also try and make the doc parser more generic.
In your opinion, would you like to see anything else in the hover window?
For completeness, could you also mention what code editor you are using?
