I think the radial menu is a little slow for its intended purpose, and seeing as we have keybinds for driver assists, ignition status, and transfer cases, I'd like to see this implemented. Alternatively/as well as a toggle in the simple powertrain UI app.
And a setting for default regen behavior upon spawning the vehicle so we don't have to change it each time
Binding the toggle to the same input as the truck compression brake should work, I doubt you'd ever come up with a situation where they would interfere. It would be good if things like EV regen, compression brake and transbrakes got buttons on the simple powertrain.
That seems blaringly obvious in hindsight. I wish I'd thought of that. Other examples of things that could get buttons are the line locks, suspension height, two-step, or even manual hubs. Cruise control has its own UI app but it could be implemented as a complete "vehicle controls" app.
