Yeah, there's pros and cons to the proliferation of Todo apps in examples. On the one hand, a Todo app provides just enough of an implementation to demonstrate the basic concepts of a tool, without getting caught up in too much complexity. On the other hand, there's a ton of real-world use cases that a Todo app won't cover. It's a tough balance - teaching basic library/tool concepts vs actual usage.

As for the help - you're welcome, and hopefully things click soon :)
