Sorry, I'm trying to reply to @JamaicaA but for some reasons it keep publishing my reply at the wrong place.

If it was possible to have the same Accountant View as the one in your screenshot, I wouldn't be complaining right now. However, switching to the Accountant View doesn't change the way the new menu is working, as you can see on my screenshot.

Your Accountant View has some arrows to display the submenu items simply by hovering the main menu items, like it was before. My Accountant View doesn't work that way, I still need to click on a first-level menu item in order to display its child items, which causes the main menu to get hidden, which is really killing my workflow right now.

This isn't right...
