One of the all-time most useful tools that I used for airport design in FS9 was the Finney Ground Crosshair Plus "aircraft". When used in combination with tools like ADE, it made precise placement of elements in a scenery a breeze. There does not seem to be anything similar out there for MSFS2020. I don't know what is involved, but would it be possible to convert the old Finney Crosshair for use in the new MSFS? If not, it would be a huge help to all airport designers if someone with the right skills could recreate this awesome tool. I would take a stab at it myself, but I am not much of a 3D modeler, and completely clueless about aircraft design.
