I had use most of the note taking software available in market and I know GoodNotes is currently in beta stage but features like editing image i.e cropping & selecting but there is lot more like copy text feature from directly handwriting as handwriting is converted to text and also something like floating toolbox as windows device have larger screen floating box will help them to continue the flow. I hope you will soon add features like cloud backup and export notes in pdf form and others.
Thank you!
