If I left click on the "ToDo" icon, I get a slew of error messages. If I right click on the icon, I can add entries from the menu, but they are all named "New Item", with no way to change them.

You need to add just a little bit more functionality to the mouse bindings, and do some error checking. Nobody likes to see a bunch of error messages fly by the screen, it makes them lose faith in the program.
