Add a notification window for saving homework

Sometimes when I think I have saved my homework to come back to at a later date. I really actually never ended up saving it. So I think what would be a good idea is after you click the save button a window type thing pops up saying "homework saved" or even just it saying that right above the button so I know that my work is saved and aren't clicking the button a million times then still worrying it hasn't saved.
