I have a lot of comments, but I also make screenshots a lot and don't want comments to show in them, e.g. when I want to make a screenshot of a chart, but the highlight is highlighting something irrelevant for the screenshot's purpose. Deleting the comments every time I want to screenshot is very cumbersome. It would be nice if there was a menu button to toggle comments under "View > ...".
This should be relatively easy to do using the Document::HideAnnotations feature from Poppler, what needs is a nice UI so that we don't get zillions of reports saying "OMG I LOST ALL MY ANNOTATIONS"
