A whole bunch of Suggestions

I presume it should be fairly easy to convert a .it file to one of the other tracker formats - they're all pretty similar.

That's not really true.  Superficially, all the module formats may be similar, but each has it's own set of features that are totally incompatible with the others.  Yes, you could theoretically convert to another format, but you'd drop notes and effects in the process.  I'm not an expert on module music, but I've heard that IT is the most sophisticated and feature-rich of all formats (IT is to S3M as PNG is to GIF), so converting it to another format, even the second-best XM, would be like converting a 10,000 color photograph to a GIF.  You'd also have to find a converter.  IT is newer and more advanced than XM, S3M, and MOD, and the very few converters I have seen don't support it, or support it only as an output format, not an input format.  Unlike other music formats, in module music a single dropped effect controller can turn the most beautiful song in the world into blaring off-key noise pollution.

Fair enough. However, considering the demand for it, I don't forsee .IT support being added to AGS any time soon.
