Atom support is now incorporated in (see below). There are a couple of sites with some challenges, but I'm sure that's tied to the hour (>1am here in Seattle) and will get resolved later today.
With Atom support, MySubscriptions, and MyMixes in, it's just testing, adding some additional error handling and dealing with the odd issues that come up.
If you scrutinized the screenshots, you may have noticed there was some overlap in the background frame in the feed display (curved frame at the bottom.) The great design folks in another part of the company have agreed to do one more edit for me, so this will be resolved for the release this weekend. Not sure if I can say the name of the team, but you can figure it out if you read some of the earlier postings
As this is a side project, it's a bit tougher to give dates, especially this week. I'm actually starting a new job next week (still at MS - details to come later) , so am in the midst of transitioning out of my old role, packing up my office, and ramping up on the new job in addition to working on Information Center.
No other features on the checklist, though, so if you check back on Sunday afternoon/evening, it will definately be here. If I post it Friday or Saturday, if you're on the email list, I'll send you a note.
Cheers,
Marc
