Hi, sorry for the late reply. As I said before, I have only been able to get @joelchan styling for the wiki links. I was important for me that the styling should work in the preview as well as in the editor. I got the following CSS from the forum.
This works with the Supercharged Links plugin , with the editor mode option enabled.
For the the more difficult part, I have the searching in the forum for some ready made alternative. Some of the plugins which have caught my eye are Juggle, Argdown, Graph plugin.
Will have to check out each one of them and see if any works.
I hope you don’t mind sharing the CSS you use for the Supercharged Links. It would be nice to see if there is something new there.
Cheers
