i read you overhaul the SPH so pls overhault the "center of thrust marker" maybee like this: that would improve the workflow and design posibilities of unsymetric crafts a lot so it's not needed anymore to analyse the thrust to mass vector in a third party program like photoshop in my case. especially with a shuttle you have to readjust the vectors for each payload wich take a huge amount of time with the curent markers. take screenshot, load it, draw line, change vector and repeat, that can be very tedious...
