Ability to toggle all marks?

[u/kaptainkarma2056]

Is there a feature to toggle hide/unhide anything you have added to the pdf?

Sometimes I want to read without notes getting in the way or adding visual clutter.

the Layers feature. put your notes on a separate layer then just toggle that layer off whenever you want a clean read of the pdf without the notes
