Works for me. "Today" fits into the current cbo without name change, "Active" & "Unanswered" both have a time element, but that is secondary to the main purpose, so I went with "&".

You are in the best position to count how often each functionality is used and if there is a group of users using that functionality more often - which would be my benchmark to weigh inclusion into personally configurable items against coding effort. I can only realize that there is a poisson-distributed usage by me on those buttons, hinting (weakly) that some buttons on the tail side of the distribution could be put into a sub-menu to unclutter the interface.
