Conditional layout

I use this to mark which students didn't pass. When a student has less than 50% it turns red, between 50% and 60% orange et. Could this be possible or is this already possible?

It is already possible Roel.
You can automatically apply colors to numeric&text based grades. From the main chalkboard screen, tap on grades , and here edit the grade you have assigned to the column you're working with.
