Good stuff!
*grin*
Coupla things -
1. Thread headings/links displayed above and below the displayed (s) - 'parents' displayed above, all subsequent parts of the thread below
2. An option to limit the s displayed at once (for my part, I would like to display only one at a time).
3. Allow more html tags (centering, lists, blockquotes, etc.) in s - I dislike getting nastygrams from Zope saying blockquote is unmatched when it clearly is matched, for example...
4. NNTP interface? Synchronization maybe, or is this already using a newsserver as a backend? *grin*?
All in all, good stuff!
