Your new Split View functionality is a nightmare. I file almost all my email into folders in the left folder menu bar. Now, when I drag emails to the left to put them in folders, I swing in and out of Split View and have a really difficult time filing my emails like I used to. It is MADDENING. Yes, I could use the Move functionality in the top bar, but it's a huge PITA and I have to scroll down through all the folders and subfolders alphabetically instead of quickly dragging and dropping. This Split View functionality was a huge fail and it really ****** me off. Do you guys even do customer testing and feedback before rolling out new functionality?
