Vehicle based improvements.
I would suggest:
Titan/Mechs and vehicles to have more sound options in their configuration. If not this, perhaps a heads up display feature for flans mod that displays when in vehicles. detecting the kind of vehicle you are seated in and displaying its info in the top left for each tab, or at the least health and fuel.

Maybe like
NotificationSound

And the cause could be things In the ballpark of health percentage = 0/100, if other vehicles near by =true/false if out of ammunition = true/false, if fuel percentage = 0/100, etc. this could serve as a way to manage health, fuel and ammo, or even for immersion in fights. ( I know I’d for sure implement this into my content packs )

As stated after the sound notes option, perhaps a heads up display that grabs the id/“short name” of what vehicle you are in and displays each tab it has in the top left but much smaller. Possibly to avoid clutter, add a HUD key to pull it up mid ride so it just appears, but let’s you still control the ride; or even just a display for health and fuel.
That’s about it for now, just something I think would improve this mod a lot. Keep up the awsome work!
