For example, its selection tool, is very handy to use: select the part that you want to edit and two icons appear which allow you to easily enlarge, reduce, or rotate the selection. Also, Inkflow uses vector graphics, so the ink stays sharp even if it is zoomed in. Further, I have not experienced any lag although I have not really created a lot of notes yet. » Read more
