There is a big problem in one essential feature.
When you creates any list, text sise will gets smaller with each line. Some people have an opposite problem. This is relelvant when you tap to enter, start writing and then clear the line - text gets smaller(or bigger).
I found, it depends on "note field size", which you set. If it smaller 100 persent - text size will gets smaller, in other way - will gets bigeer. You need to fix it, it is shameful bug for such a big company.
