...or simply use one of the spen buttons when easing. It is annoying and too easy to erase parts of files when pinch zooming or two fingered panning. Sometimes it thinks you are doing a one fingered erase and its hard to notice that you have actually deleted an important part of your sketch.....sometimes you dont notice until weeks later you re-open file and some is missing!!!
It’s still on our todo list to support this directly, but I wanted to mention that it’s currently possible to password protect a note in a roundabout way: by importing a password protected PDF into the note. This will password protect the note with the password of the PDF. You can even delete the PDF from the note and the password will remain on the note.
