Nautilus has ruined Notes Writer Pro

Since Notes Writer Pro has moved to Nautilus, the page curl animation has gone. No option to open pdf in reader mode with shortcut to the content menu etc. The reader mode keeps crashing. They have also removed the option to highlight and turn the pages of larger pdf files in reader mode. It is a shame Nautilus has spoiled the great app!!

Something need to update

Hello..

Thank you for all the great work you’ve clearly put into your wonderful app. I’d like to suggest adding a feature that allows users to open multiple books, folders, or files at once by selecting all or selecting multiple items.

This would save a lot of time, especially when dealing with a large number of files.

Thank you for listening to my previous feedback as wellβ€”you’ve improved the app so much! 🀎
