This should be an easy plugin. I’d love an even quicker way to enter internal links: in addition to double-brackets I’d like it to recognize any WikiWord, which is a word with leading Caps and at least one internal Cap. I realize this isn’t to everyone’s taste, but I like it much better than double-brackets on every link.
I fits my brain to give my pages “CodeWords” that look like that, and it’s four characters less typing. I know this is essentialy the same argument as @ links like @page. But it’s an optional plugin so nobody has to use it if they don’t like it.
