"seamless" zooming in Full Screen

Just a question: I am mostly working with Scrivener in Full Screen mode. I set the font size to 18pt just to fit the zoom feature: With smaller font, I wouldn’t get a fine enough scaling in the zoom pane (it would be above 300%).

Would it be possible to make the zoom setting fully flexible, or that there is at least a smaller scaling available above 175%, say, 250%, 350%, 450%?
Or maybe I just missed that feature?

More flexible zoom settings are on the list for the future, although it will probably be a while (2.5-ish perhaps).
Best,
Keith
