All annotations should be displayed if viewport size is not so wide.

Some users view CT/MR images using sheet view layout with 3x3 or more sheet size.

They want to see all annotations if they select such sheet size.

But ZFP does not display all annotations if viewport size/sub-viewport size is not wide.

I see a CT series using 3x3 sheet view on 1M monitor, UV does not display an annotation even if the sub-viewports has some free space.

So I believe ZFP can control such space to display annotations.
