@Writers: personally I prefer the actual process, I don't want the simulation to restart because sometimes I adjust some simulation parameters (gravity, winds,...) before restarting or simply make an export to see a render result of simu. So I prefer to decide If I must restart the simu or not

@Tomyee A complete save could be interesting at least for the clothe drape. I think it must be easier with static simu than in animation simu. Sometimes my drape is correct, I continue and I want to come back to the previous drape state. The only solution I found is to export before trying something but that's mean a new simu if I want to improve the drape.

Good idea with pinching and magnet tool !
