RTM is a great tool. However I'd really like to see more sorting options for the FF extension and Gmail Labs. I'd like to have the names of my lists as headers and be able to manual move & sort the tasks in various ways like in outlook for example. Is that possible now or are you planning that in future? Seems strange that the names of the lists cannot be seen, at least as a option.

Also the way tasks are input in the gmail labs should have an easier way to choose which list you want it to go in plus have a default list setting.

Just my 2 cents
