Tree View Sample: Ability to display a badge

[kubawolanin]

Hello,
In the tree-view-sample there's a nice example of how to create e.g. a Refresh button on the tree view.

I'd like to add a badge with a number indicating total count of the items that are stored in my tree.
Similar thing is visible on the "Changes" tree view for VCS:

I'm wondering whether it's possible for me to have that too.
I'd appreciate any help.

EDIT: Just found that in the Git extension it's called countBadge:

Is it exposed somewhere?

Thank you all for the tremendous work!
