In order to get multiple lists working, you'll need to go down to the lower-right corner of each frame and select a different list to be shown in each frame. Otherwise you are just using the same list in different frames. I'm totally with you that this UI/UX is not ideal. If Google exposed more of a Web API we could do more. There are plenty of good web-based todo lists, what I wanted specifically was to beef up Google Tasks. However, now that you mention it, there may not be a good multi-paned todo app out there. Someone should make it. Maybe me, maybe you! ;-)
