Hey there!
amazing plugin, use it in my project because it have so many use cases! I have a question for you,
Can you expose the “CrouchedHalfHeight” in a function that can be set? because currently it cant be set through blueprint and i think it might be a good addition? Or a function that automatically offsets the capsule based on the half height instead, so you can change the capsule components half height and it allow it to offset too.
For now i created my own function but i just thought it might be a good addition to your plugin! 
Anyhow, have a great day/night!
