Last night, some updates went into the released version of BeTwittered. Two features are added. The first is that replies and any other "@username" reference is now highlighted, and clickable. Clicking an @username reference will now take you directly to that persons Twitterhome page. Also, there is now a settings page. Click on settings, and you'll get, currently, two options: You can choose to logout of twitter, and you can choose to turn off user pictures in the timeline.
Related news: It appears that google may have fixed an issue they were having with their gadget directory. Since last night, BeTwittered and "Amazon Top 10 Geek/Tech Books" are showing up again. This means you can use "add stuff" on your Google homepage to get these gadgets again (and a whole lot of others that were also missing)
