This is a nice app, and the best pdf viewer i could find for windows. that said, the scrolling behavior sucks on both windows and a debian build i tried it on.
I haven’t used Windows for at least half a decade, but I remember using Sumatra PDF, and thought that was the best pdf viewer for windows.
It's free, extremely light -weight and feature rich. And reads a lot formats- epub, mobi, cbr, you name it.
You should definitely try Sumatra PDF.
SumatraPDF supports basic annotations as of version 3.3 https://www.sumatrapdfreader.org/docs/Editing-annotations
In fact in the second case, I recommended the app, and my friend rejected because he felt the touchpad scrolling was off.
