To me, view mode is useless, because it doesn’t allow to move past the cursor, and doesn’t move cursor if you try to move past it. Which locks you to your cursor position plus the amount of lines that can fit on screen before and after it. If you start view mode in the initial position (0,0) it is pretty much useless, because you can’t move neither down or right.
But I use view mode, because I’ve binded select-view command in that menu. So vs selects entire view for me. It also bound to Alt+%, though it’s harder to use.
I also rely on view-mode programmatically to center view after successful search or jump in my plugins.
