vertical text - (edit cell -,for,at cell - rotate text)
Add standard excel feature ( edit cell - format - rotate text ) to any degree, or at a minimum 90 degrees or multiples of 45 degrees. This feature is becoming ubiquitous, even finding inclusion in functionally inferior products (I.e. google sheets)..due to its extreme usefulness in formatting (column headers to enable thin columns where filtered cells contain 1/few characters). This allows for maximization of coveted screen real-estate...which is of even greater premium in a mobile application where users have but one, smaller, screen with which to analyze data.
