I've been working on Sid (obviously) for the last couple of days – I made some (finally) very nice improvements to the interface. In the last few versions, the settings for the conversation were done in a drawer. The drawer was almost as large as the document window, which was awkward and just not elegant.
So I decided to change the interface to a set of tabs: Post, Preview, and Settings. Post obviously has the form for posting, Preview gives you a preview of the body of your post, rendering the HTML, and Settings replaces the old drawer with a tab. It's quite nice actually.
I'll be releasing version 0.8 sometime today, so check back if you're interested.
