Create new task types

Hi

I really love the app, but I really hate calling everything an "issue". Oh my god, I will get depressed and other people will attack me if I call every great idea an issue. I found a video that said I could "add new task types".
Fantastic!
No more issues!

Except, when I tried to do it, it won't let me create a new task type.

Honestly, Issue is awful. Please fix this so that I can continue to use the app, and recommend it to other people.
