Hmm, sometimes it's the most obvious things that you don't even realize are missing. I guess we were all looking at the finer details rather than the most basic functionality. It's been a week and you're the first one to notice this!
The ability to create a new list does indeed appear to be missing from the page. You can edit or delete a list, but you can't create a new one.
Hahah, it happens, don't worry I'm sure I'm not the first one, who spotted this, but others rather reverted to old page I guess.
In fact I like the look of new one, good job.
