To clarify, I don't manually keep points up to date. There's a script that reads the PDFs published on the warcom site. (well, not the pdf file but their raw text content) This makes it very easy to update points & datasheets, because all I need to do is copy&paste the new files.

I can understand the difficulty, and that's why it's so sorely needed. Validation of list and wargear with a coherent output/printing is a large part of what people will be wanting. Seems only the official app is offering that at the moment (though the view list format stinks), and GW putting it eventually behind a pay wall will be a huge opportunity for a third party application.
