MajorMagee, old settings still work. I wouldn't dare to break them knowing how much work you put into adding reticles to various aircrafts. And speaking of work - the new version simplifies positioning and calibrating of reticles. Too bad I didn't implement it earlier.
I can send it to you if you are interested.
As for clickable cockpits - I've looked into it, but not too much as it goes beyond the graphics features I'm interested the most.
I tried to find and somehow reuse CFS3 code which shows labels when you mouse over certain gauges, but haven't been able to. However even without it I could write my own code to track mouse pointer over specific objects -- that's not too difficult.
I also tried to find the code responsible for handling control commands, so I can send them directly, but didn't want to spend too much time on it. Perhaps it could be simpler to simulate keypresses and let CFS3 engine handle them normally, like it does when using AutoHotKeys.
So clickable cockpits are sort of possible, but do you really need them?
To me they feel like a gimmick. Interesting to try a couple of times and then never come back.
