@Hecks: did you notice that the search engines do not cover all available newsgroups? They are missing a lot of very important binary groups, like "a.b.u-4all". With AltBinz, there's no way to download anything from the groups not indexed by the search engines.
This is definitely a good reason to implement header downloading! This should not be difficult anyway - AltBinz already supports getting the list of newsgroups on the server, but what for? What's the point of doing that if it can't display the group headers anyway?
I would like to see header download implemented, because only with this feature AltBinz could really be a competitive product to the established programs. There are many posts you simply can not find with binsearch, newzleech, etc. and I always have to use NewsLeecher just to find these postings. That's pretty annoying and if AltBinz could show me the headers in a group, it would all be fine. Also, this would make it possible to read text messages related to posts (not just the NFOs), which also would help a lot.
Regards!
