[Plugin: Crayon Syntax Highlighter] Two things that bother me

First I want to say, that I like this plugin, it’s very fancy. But there are two things which bother me. One point is, that it is not possible to use the
pre-tag because the plugin effects all of them even those with now class attribute. The second point is that strings in c, cpp, etc. are not always recognized correctly (http://s1.directupload.net/images/120710/egya99qh.jpg)
