At the end of a trading day, I like to ensure there are no open orders. I trade multiple accounts with a prop trading firm and currently have to check each account individually. It would be possible to ensure there are no open orders on any account with one glance of the Accounts widget if a column were added that displayed the number of open orders on each account. You may also want to add a column to display total contracts traded for people that screenshot their trading results at the end of the day.
On the top right corner, where your account info is, click on that and it allows you to exit all positions.
