Of course, this is only my opinion.
I see the only one purpose for vertical offset. it is a big FOV view in AltAz mode. It is really useful and looks great.
But try to use this feature in real life. For example, typical lecture for children. First, you show great AltAz view of the night sky. You tell about well known stars and constellations. Next, you show the moon. Why is it distorted? Hmm... Then turn On the Ocular View to show some galaxies... Why the half of ocular is below the screen border? Is it really what you want to show? Finally you go to the settings and switch off the feature as it makes any view in small FOV significantly distorted.

Just take attention, we even do not use EQ mode at all, but see how the potentially great feature causes problems.

As for poor me... who needs frequent switching between Ocular View, AltAz and EQ, who uses all the possible range of FOV...
I need a fast switch off the view offset, especially for EQ. If I really need vertical offset, then I need horizontal one as well there as I'd prefer shifting the picture on the diagonal.

Small FOV, ocular view, camera view, and EQ mode in general need viewport to be switched off. Perhaps sometimes the possibility of shifting the view is useful here as well, but it is definitely not the mainsteam. And current solution of switching the feature via F4 - Markings - mouse scroller looks unfriendly.

So, now, after imaging several scenarios of extensive work with the porgram, I'd like to propose even more strict limitation of viewport offset usage. It should be used for big FOVs in AltAz mode, perhaps smoothly changing the offset to zero along with FOV decrease.

Thanks for reading.
