In cases like :
Screen Plane issues with DLVP in 3D
where I can't use a DLVP crop, or many other situations,
I hardly miss :
1.
An option to Fit View to only Visible Elements.
(by ignoring all see-able Elements that are Grayed Out)
2.
An option to Fit All Geometry
although I currently have a Selection.
(Which may be a complex Selection that I don't want to lose)
So like in C4D or else where I have separate Tool Icons for "Fit Geometry" and "Fit Selected"
