I might make BulletSettings an inherit-able class, sure! Probably not before the jam, though, there's a ton of editor code behind it. I didn't really anticipate people wanting to add much more functionality to that side of it 😅 is there anything in particular that it doesn't do that you'd like it to do? I modelled it mostly off the particle system, though there are a few missing things (like animations and trails, etc - incredibly difficult to implement but I'll get around to it eventually...)
Understandable. Currently there is not that much I can think of outside of the line issue.
