I used iPad OS’s markup feature on a multi-page PDF for the first time this morning. It works reasonably well, except that there’s no way to hide the overview, and it’s positioned where I usually rest my wrist to write. The palm rejection is not perfect either, so when I try to write something, it sometimes interprets my wrist as a tap, and sends me to another page.
I wish there was a way to hide the overview, or move it to the left side of the screen. It could even be configurable based on which hand you use to write with.
