navigator pane: show item count

We have a problem with a rather common solution - an item count next to the item it relates to. In order to avoid clutter this is a typical show/hide option in most applications. Yes, I know that an option introduces a new code path that has to be tested. But your solution, hiding the item count at the end of the list where almost no one will look for it, adds a new code path as well.
So please either implement the common solution with configurable item count in the sidebar or don't waste any more time on an uncommon solution that almost no one discovers but then tell the users that don't want to implement it.
