I would like a way to use columns from other boards in the formula column.
Hey @Soroh,
Are you interested in utilising mirrored columns in your formula column? If so, can you specify which ones? I ask this, as it is currently possible to input mirrored columns in the formula column 
It’s a one-to-many so mirrored columns won’t help. I have one board with providers, another board with their students. On the board of providers, near each provider name, I want to display the number of students assigned to them on the students board.
