They should add a way to do diagonal buildings (roads, terminals, taxiways, decorations check-in desks, airplane stands, etc…) it would be really cool like to have an X Shaped terminal with diagonal stands.
Also they should add an way to configure with runway letter bc like if I build an airport with an GA Area that has it own runway and an terminal that has 2 runways on the 1st runway of the terminal it would be letter C (Center) so I just like to request that and fix the roads that are very glitchy like u place an object that needs roads on the side of the road and the road make like squares or something like that.
