Jereme,
The RSS Widget is super close to something I've been wanting for a long time now.
Ya know how we have the 4 newest videos listed on the homepage...well, it would be sweet if we had the capability to scroll through those videos without leaving the homepage. Basically, it would be the exact same thing as your RSS Widget, but instead of going one video at a time, you would go 4 at a time.
Netflix now has this for their new releases section.
Anyways, you should think about doing this for your next add on...I think it would be a big seller.
