mission editor improvement required

[Pluto]

I have realized that the entries you make in a mission, in the mission editor are not kept! For example, if I change something in a mission, all the values that I have previously saved, are gone.
If I have put the AA range (hide) for ex. at 6000 m, it is again at 0 when I open the mission again for some other changes.
That means for each change I have to reset all the AA guns to what I had put before. That sucks!

And something else, the searchlights are shining really weak, only visible from about 1000 meters distance! The static planes have no markings and you cant choose any!

I think these points are strongly recommended to be changed.
Among many other issues that I cant think of right now.
