I've experimented with Claws and Pan. Of the two, I like the way Pan looks a lot better. Claws just feels like the News capability was added as an afterthought.

Unfortunately, Pan is giving me problems. Aside from the little things like not being able to see all of the full configuration dialogs, and not being able to use some keyboard shortcuts (my N810 doesn't have a Delete key, for example...), it also crashes whenever I try to save an article.

I normally read news on the subway, where I don't have connectivity, so I want a reader that will do let me do the following:
1) download full headers and bodies for all new posts with a single command
2) display them in a threaded fashion
3) allow me to read through them and easily mark articles I want to keep
4) delete all unmarked articles with a single command (either globally or per-newsgroup would be fine)

I see how to do 1 and 2 with Pan, and if I could figure out 3, I can probably get 4.

Can anyone offer some hints on flagging articles to keep? Or suggest a newsreader that can do the above?
