There is also a Discord server set up for the development of the mod, which would give you direct access to the team.
Also, at this link:
https://github.com/Merker6/community-a4e-c
Is a direct link to the Github repository, which contains Cockpit Arguments which may be helpful for your development :)
If there is anything I can do to help, let me know.
Cheers
