Considering you can edit columns in the Table view, this seems like a basic (and easy) thing to add to Hubspot CRM. By not including this as an option at any level, you are rendering the board nearly useless for about 40 percent of users. Our weekly sales meeting typically starts with our team examining/discussing a board of potential deals sorted by Owner, then by Priority/Amount. What is the point of being able to sort by Hubspot Owner on the board if you have no clue who owns the deal without clicking on it?
This is a must add.
