I'm not a programmer, but sometimes I have to work with .asp and .aspx web pages. It'd be nice to be able to edit these with Code Writer.
ASP is a Microsoft coding language that allows for C-based coding on the web (I think). The official site (which I believe includes documentation and code exapmles) is http://www.asp.net/
Additionally, please support .master pages. They're a kind of template page for ASP, written in the same languages.
