Yes actually today I called with a different question leading me to the new build also. For my overnite positions I couldn't figure out how to toggle to keep the p/l ongoing and not based on current day p/l. Tech support told me the new build does it automatically that way now, but as you say, the current p/l is no longer there, just the unrealized p/l.
You can see your realized p/l by clicking the account labe on the menu bar.
