I have released version 0.34-3 of sfsim.

Reentry shockwave visuals are now integrated into the game! The shockwave’s shape changes with the vehicle’s speed, while its brightness depends on the rate at which energy is converted into heat. Getting the shockwave to conform to the spacecraft’s wind-facing surfaces was particularly challenging. For technical details, see my post about shockwaves.

Let me know any feedback and comments in the sfsim playtest discussion forum.

Don’t forget to wishlist sfsim!
