I have no idea how hard this is to code but I know that this is wanted feature.
Currently we only have 3 types of preset view options that we also had in Il2.
This feature already in exists in CLOD BUT at the moment we must hold in a selected button and then move the mouse forward and backwards to zoom in and out. This is not desirable in combat. Instead a "zoom in" button and "zoom out" button would be greatly appreciated!
This feature exists in Rise of flight and is great! Here is a video
This is how it looks in CLOD
Its a great feature but currently way too complicated to use in combat!
