Missing features

Is it really true that ADE is missing these basic features?:

1. adding a note that is not attached to the highlighted area, but just sits besides the text.

2. the ability to zoom however much you want, and not being forced to only zoom 1x, 1.5x or 2x but for instance 126 %?

3. a fluent scrolling feature. When you scroll, it is lacking much, that it takes ages to look through a book.
