Main Window

This shows the groups pane on the left, the header pane in the above right, and -- since this is, after all, the screenshots page -- the article body pane is looking at a pretty picture posted to alt.binaries.pictures.wallpaper.
Also note the green icon of two joined puzzle pieces in the thread pane: it denotes articles with complete binary attachments. (Incomplete multiparts get a single red puzzle piece). This way you don't have to count all the posts in a multipart binary for completeness and you can also filter out incomplete and no-attachment articles.



Leeching

Pan's original claim to fame was frenzied, thousand-post leeching. In this screenshot, a user is queueing a modest number of images from alt.binaries.fine-art.fractals to download into a directory of his choosing. Typing Shift-S will skip the dialog altogether.



Reading Articles

Closed envelopes are unread articles, while opened ones are read. Articles with gold envelopes are new, grey ones are old, and those in boldface have new replies. When all the articles are read in a subthread, the subthread is greyed out. And if the thread is closed, then at the end the subject is a number in parenthesis showing the number of new replies. The green disk icon in the second column denotes articles that have already been downloaded and are cached locally. This comes in handy for offline reading.



Internationalization

As of version 0.12.0, Pan can now post and read messages in arbitrary charsets and fonts. There are also per-newsgroup default charsets to use for articles whose charsets aren't set properly.



Navigating Articles

This screenshot just shows what options and shortcuts are available for navigating through articles, threads, and groups.



Article Filters

This shows the different article states that you can filter, and how to show the results that match. The Filter menu has all kinds of settings, and the most popular are repeated in the toolbar.
In this screenshot, everything is turned on except for articles with complete attachments. (This is a popular setting in alt.binaries.*) Clicking on the "Show Just New Articles" button in the toolbar would change the filter so that only new, complete attachments were shown.



Task Manager

Pan lets you queue downloads and run multiple downloads at once, such as interactively reading group A while downloading headers in group B and leeching binaries. The Task Manager allows you to see which tasks are running, re-order them, cancel them, or to pause all tasks to go offline temporarily.



News Servers

Pan allows you to connect to more than one news server at once, and to maintain a different .newsrc file for each server. This shot shows how news servers are added and edited.
