Hi Pilou, unfortunately I don't think it's practical to add a snap like that which was always in effect, it would probably be very confusing if it snapped like that under regular movements.

Too many mysterious snap points happening automatically can be a problem.

Something like this will probably need to be set up with a constraint solver, SolveSpace is a good one to use for now. In the future I'd like to have one directly inside of MoI as well.
