When you select the camera node the camera icon in the scene default view has a “field of view” icon attached, so you can at least get some idea of where the camera is pointing without having to jump back and forth between scene view and render view. However when you select the Import node in order to tweak camera position and scaling to try and get some sort of match to an imported camera move the “field of view” bit of the camera icon disappears.
Given that the remaining camera icon always points left to right it isn’t helpful for anything other than position - could you have the “field of view” bit added to the Import node display?
Given the other issues with import this is relatively trivial but if it was an easy change (given that it’s already happening in the camera node view) it would make things a bit quicker.
