It would be great if there could be permalinks so that I could keep windows to different sections open all the time.

For example:

https://web.any.do/all/time - Would bring a user directly to has "All Tasks" list organized by time.

https://web.any.do/personal/list - Would bring a user directly to his "Personal" list organized by lists.

https://web.any.do/priority - Would bring a user directly to his "Priority" tag list.
