Thanks for the input. There's definitely a lot more that can be done, especially for those who need to track a large number of packages. More features, possibly requiring a login, is something I've thought about, however this super simple service meets my needs perfectly, and my guess is that I'm not alone. Depending on how this goes, I'll be looking at building out more functionality.
