I see that you are using subversion. Why not use git and a github account for the code. I used subversion a few years ago after CVS. But git is a lot better ;P
Is it possible to add support for name and not only id in the shortcodes
Today:
[wbcr_php_snippet id="xxx"]
Feat:
[wbcr_php_snippet name="mysnipp"]
Something to fix?
