Looks logical, and more compact. I like the ratings option as it should allow sorting by taste, and not necessarily alphabetically.
Actually, I hope it allows for filtering by other criteria also, i.e. author, category or theme (OS, Holiday, General, etc), colour (?) are a few I could think of.
One thing I'd like to ask for is perhaps the ability to be used on 600 pixel height screens?
Got myself a new netbook, and WB actually works great on it, despite the limited power of my netbook. It just gets cut off at the bottom .
Actual screen size is 1024x600, so it can go a bit wider. It's just pretty height limited.
Sounds like it needs a scalable interface.
All in all, I think it promises to be quite fun and am looking forward to the update... whenever it becomes available.
