Ability to start a blank page straight away
iOS 11 allows one to tap a locks screen and start writing notes
I suggest,
The ability to hard press or when clicking the icon to open the app to a blank page straight away so you can immediately start writing
This can be set up as an option in the settings.
The settings would allow you to choose default paper &/or cover which would later be saved when you finished writing. This way you don’t waste time opening the app starting a new doc, choosing the paper, cover, naming the book etc etc.
GoodNotes 5 supports a new “QuickNote” feature. You can double tap the add button in the library to start a new blank note right away. Our new app supports Siri Shortcuts, which allows you to create a shortcut for a new QuickNote in the Shortcuts app. This way, you can add a button to your iPad homescreen or to the widget center that will create a new QuickNote in GoodNotes right away without having to access the app. The option to create a note from the lockscreen is restricted and not publicly available to third-party app developers unfortunately.
