I have always had problems on laggy computer with a double build or a double destroy in creative mode, I would LOVE for someone to add a mod to eliminate that by making it so you can only place a brick every so often, Im not sure weather with the lagg the bricks are placed really close together, but if they were then you could make it so you could have an options bar so that everyone could set it to there liking, or turn it off so they could tower or something like that

This would really help and im not even looking for it to win a contest but everyone with a laggy computer that plays minecraft will know what im talking about, thank you

(p.s- if there is some mod that does help with this double destroy and double build problem then please comment me a link or its name and where to get it, Thank You)
