@skulpture I have asked for this years ago - it's kind of vital if you have a complex setup where you have a frame jammed with precisely arranged pieces to go to multiple LED walls, or specific shaped projections. Eyeballing is so slow and just not accurate - the info is there we just need to be able to type it in - and even better let us load it from json or csv - when you have to do lots of slices mistakes are easy to make - loading from a json means no errors.
