Since you are already using the codejock syntax editor control, I think it would be great if that could be used to view/edit other types of script files in the HTML pane, such as PHP, CSS, JavaScript, Python, etc. I imagine setting the file extensions that open as plain text scripts in the editor would be the way to go.

 

This would be useful to me as a web developer because I could organize source code in a conceptual outline, include code items under task items, search for functions/snippets from within IQ, etc.
