I've ported activeRenderer's preferences gui to liveTopics yesterday. The liveTopics Preferences page now features 'active' outline wedges to get additional information on liveTopics options when available.
Matt has added a nifty 'Suggest' button to the topic selector.
When I click the Suggest button, liveTopics scans the currently edited post and displays a list of the post's words that match entries in the topics list. I can then check the ones I want to add as topics for the current post.
