When I add a new item through the "new" button, I would like to have the page auto-refresh adding the item.

Currently, if I use the "new" button, I have to refresh the page to see the item. I'd like it to automatically do so, if the item is a new todo or an appointment for today. Similarly, when I mark a todo as done I'd like the corresponding "appointment" (if there was a date and time) to be marked done without having to refresh. In fact, when marking a todo done, I'd prefer to have it change to done, and then fade away, like forgetting it does.
