I just posted an update to ColdFiSH on RIAForge. This update is mostly just spit and polish on it what is already there. I added bolding for keywords (yep, huge deal), updated the default font (hope you like it, if not, you can change it), fixed an issue with viewing the text plain in case you are in firefox and want to copy code with all the spaces and tabs in the right place, and updated the navbar a tad, and turned off line numbers by default I think it looks better without... if you like them then it is easy enough to set showLineNumbers to "Yes".
Here is the result.
As always, please give me your feedback if you are using ColdFish (and if you use BlogCFC then you use ColdFiSH.)
