I, like many others like to browse community labs and new and noteworthy.
But if you want to see all the worlds that have been uploaded since last time you browsed around, it can be quite annoying. This is because the scrollbar is going all the way to the top every time you try to go somewhere new.
This (at least for me) makes the time looking for your next world to go to mostly consist of trying to find where the last one was. slowly scrolling down until you find how far you've come down the list.
The favorite avatar lists seems to stay between worlds for me. So why not worlds? Please?
