When I woke up this morning, Remember the Milk had a whole new look and feel! Better usage of screen space, display of tags and a nice keyboard interface, too.
You can read more about it on their blog, which includes screen shots. Its a much slicker user interface.
If you haven't checked out RTM yet, you should. And if you passed it up before, you should give it another look. The interface continues to get better and better and it is still free! Combined with Jott, you can rule the world!
In my opinion, I think they have Google-ified their interface some. I still maintain that they are building a great product and waiting to get bought by Google.
