I just need “categories” shortcut button as in Goodnotes 4. This is THE MOST convenient thing that this app MUST HAVE. Many people have a lot of files and folders. We just want to reach to the file we want to use instantly when it pops in our head without tapping “back and back, and back, and back” over and over just to reach the main “Documents” page first. That’s why the Goodnotes 4 has advantage over Goodnotes 5.
