Especially since there is no hotkey for this action. I would sacrifice the Mark as Read/Unread (those have hotkeys anyway) or the Message Recall action if the aim is to keep the entries at a certain level.I have had several requests from users already using the Standard client and this was the only option they miss so far.
Speaking generally the reduction of menu entries got a great feedback from standard client users.
My workaround is to add the action icon to the view navigation toolbar. Works in some way too.
