V4 does behave exactly as annotating a PDF file - down to the band across the screen in the upper 3rd of the display. I added pages then scribbled on them. It doesn't capture every stroke at first. Letters turn out kinda incomplete. This lasts just a second. Soon after it records every stroke. After 5 pages, it hung requiring a reset. Reloaded V3.
The icons in the toolbar are nice.
