I think it will be helpful to show the A1 mini’s plate and exclusion area even when other printers are selected. For example, when I load model parts onto the plate of an X1C, I can try to fit the parts into the A1 mini plate plate area if it’s possible, so that the print profile can be used as is by an A1 mini printer as well.
The A1 area can be shown by using a different color and/or dashed lines, and labeled as A1 mini plate area.
