My feedback to Yahoo/Turbify, here are the most effective points to mention so their product team understands the issue:Request the return of Message Tabs: Explicitly ask for the option to turn "Message Tabs" back on so you can have individual close buttons (X) for each email.Explain the Split-Screen flaw: Let them know that the "Right" and "Bottom" preview panes need a dedicated "Minimize" or "Close Pane" button so users aren't forced into the List view just to clear their screen.
