On the engagement leads page, I currently am able to see:
  • Contact, Company, Tag, Connection, Connected To, Stage
For me one of the most important columns would be
  • Account Industry
I'm sure many other people would also care a lot about things like
  • Number of employees
  • Headquarter Location etc.
So ideally the user would be able to choose which colums to display and also be able to click on the column to sort by it.
