This is stuff I have planned for future versions of the program. Contact me and vote for your favorite, or else suggest something else.
Filtering rules. This will be a large and extensive feature, and it’ll take me quite awhile to implement, but it’s at the top of my list of priorities. I plan to make it possible to killfile a thread, automatically download messages of interest, assign points to your favorite posters and topics, watch or highlight threads that you’ve participated in, and so on.
The ability to add attachments to outgoing messages.
Dragging a URL out of the message view should create a .webloc file.
The user should have the option to apply the killfile during downloads.
Message printing works, but just barely. I plan to improve it to include header strings and tweaks to make it more robust.
Reply via e-mail.
The ability to add arbitrary headers to messages you post, such as X-No-Archive.
A search function, so you can find messages based on criteria you supply.
A window that will let you edit killfile entries.
A window to let you select newsgroups to post to.
Decoding and displaying X-Face pictures, and the ability to add them to outgoing messages.
Proper handling of the Followup-To header, including the ability to add such a header to messages you create.
Handling of news: URLs. I’ll probably re-direct them to Google groups for message-id searching and browsing.
