Mark Notification As Read

It Would Be Good If There Be A Button To Mark A Notification As Read Or A Checkbox To Do The Same To Multiple Notifications At Once. Having To Click Every Notification That You Want To Mark As Read And Having To Go Back To The Notification Page Because Opening Them In A New Tab Doesn't Work For Marking Them As Read Then Wait Until The Clicked Notification Changes To Read Becomes Pretty Annoying After A While.
